In my 300RUM, I run 92gr of Retumbo with Norma brass, and Fed 215m, pushing a 200gr Accubond 3145fps with stellar accuracy, like .25 moa. This is from a 26” barreled Fierce Fury. It is an elk hammer.
Thanks Gavin and Guy for showcasing one of my most favorite go-to powders for my 28 Nosler. Heavy for caliber bullets and rutumbo get along very well in the 28 Nosler and puts more speed out of the muzzle than anything I've used. Keep up these great videos!
best of luck with that it is hard enough to find it here in Australia where it is made goes by the name of AR2225 here. a lot but not all of the hodgdon powders are rebranded ADI powders
I’m using Retumbo in my 7mm Rem Mag Tikka T3X superlite 23.5” barrel. I’m using 72.5gn in Peterson brass shooting Berger classic hunter 150gn going 3122fps with an SD of 7.1 I’m finding I can get the first two bullets touching at 100m then the third hangs out there a little but still shot 0.58 MOA. Took it hunting and shot a red deer stag, a fallow deer buck, a pig and a yearling fallow spiker. I love it. 4 from 4 hunting.
I feel like you just told the world about our secret fishing hole. I use this powder in my 338LM and 338LMAI. As you might imagine it takes a lot of it to make things happen. Very rare in southwest Montana at local suppliers. Thanks for a great job, next time don’t give up our fishing hole.…
I have been using Retumbo for years now. First in my Sendero 7mm Remington Magnum for lots of years, and then about 2019 started using it in my Savage 110 Tactical chambered in 6.5 PRC & also in my Bergara B-14 HMR chambered 6.5 PRC. Punching 20"x24" steel plate up to 1250' yards with .140 grain Nosler RDF's. Holding about 20 thousands from lands, loading 56.5 grains of Retumbo, I really like that Bergara!
Just got some and was wondering if 140s or 35 a tips work with it…6.5prc waypoint 24” carbon..my 130tmk run 3250fps and vaporize jugs at 200 killer…I’ve got 85gr rdf’s loaded for my carbine…went for the bergara and the look of this waypoint got me but actions not near as tight and smooth as b14…and I’ve shot 2 in creed and .300wm and both were impressive…
Retumbo is best powder out of my 6.5 PRC RPR using Berger's 140 Hybrid and 153.5 LR Hybrid bullets. Pushing 140's with 58.0 grs with a COAL of 3.045 gave me 3003 fps, ES: 9 and SD: 3.7 (Brass: Lapua, Primer: CCI 200). 57.2 gr. pushing the 153.5's to 2944 fps with COAL at 3.056, ES: 16, SD: 5.9 (Brass: Lapua, Primer: Federal 210). Temperatures at 68°F, Density Altitude: 165 ft.
Good to hear. I've tried 8133 with 153.5 and couldn't get enough in the case. RL26 had plenty of room left. Figured Retumbo might be the Goldilocks powder for 6.5 PRC heavies.
Savage 110FCP HS Precision Bolt Action, 338 Lapua. 92.5 grains of Retumbo under a 285 ELD-M, touched off by a GM 215M primer. SD of 3 and ES of 7. 2798 FPS. I'll be starting load development on my 300 WM's and 300 PRC now that I'm seeing it starting to show back up on the shelves. Back during the shortage I changed my WM's over to RL-22 and haven't got too much into LD for my PRC.
The funny thing about the RUM is the heavier the bullet the better performance you get out of it. I have a 32” barrel on my RUM and I’m getting 3100 fps with the 245 Berger’s with no pressure at all. Awesome performance I use it in the light ELR class out to 2500 yards
It isn't funny, it makes common sense. There is more consistency in bullet weight with heavier bullets. They also have more bearing surface. It's a no brainer they will shoot tighter groups.
I use retumbo for my 7 mm rem mag and my 300 win mag , great powder 👍😊 I get a kick out of all these new cartridges coming out, I think they make them to catch the shooter, nothing new.. they already have old cartridges, that do the same thing.. 243,270 , 30-“06, 7 rem mag and 300 win mag.. it’s all about bullet placement and trigger control.. people get carried away with all the b.s.. there’s a lot to be said for flinch factor.. I use 7rem mag with Bergers and it will do for just about any game.. getting a gun with the latest greatest cartridge, doesn’t make you a better shooter, practice does..
I used Retumbo with the 264 Win mag with 130, 140 and 156 gr bullets with excellent results. The 130 gr Swift Scirocco was my go to bullet, loved how well it performed on game.
@@stephanlopez7640 It is long. I use the AICS magazines for magnums which have room to load out past 3.8" if you want. Weatherby throats are deep so going with a magazine fed chassis gives you a little more room to seat those bullets out closer to the lands
When I started reloading for my 6.5PRC very body told me to use Retumbo. After 60 rounds and almost have a LB of Retumbo with no groups under 1moa I change to 7828ssc. It took me 15 shots to get a group under ½moa with the 7828ssc.
I tried it in my 25-06 with a 120 grain Speer Grand Slam, I haven’t chronographed it yet but it really flattened a Whitetail buck that I hit too far back
I’ve found retumbo works great in all of my longer barrel rifles, my 300 WM loves it out of a 26” and even my 308 preformed decently out of a 20” with larger grain weight bullets
I have a couple lbs of retumbo and haven't used it yet. I'll be loading 300 PRC soon with it. Only have 1 box of factory 225g. Hornady match to compare it to. Ruger RPR unfired thus far.
Wow. I just looked up the Sierra load data for the 250 gn SGK. In the 5th edition it shows a max charge of 98.8 grains of Retumbo. The 6th Edition however says max charge 90.1 for Retumbo. That's one heck of a change. It only shows a tested overall length change of . 010"
Are you kidding me? I have been looking for Retumbo for 2 years now. Where are you guys finding it? Same for the H1000… waiting on powder to start reloading a .338 LM.
I use this for my Rem 700 trued and barreled n chambered in 6.5X284 Norma at Bartlien barrels and it’s been great for me. I get 3080 with 140 vld Bergers. I also load in a 300 RUM for pushing my 230 berger hybrids at 3000 fps it’s been a great powder for me just wish it was more available. Luckily I still have 6 lbs left. Good stuff Gavin!
I was using it in 300 RUM, 300 win Mag and 6.5 PRC, but have not seen a bottle since 2nd quarter 2020. Have since switched all my loads to other powders
I use Retumbo in my 25-06 with 110 grain bullets and in my 300 RUM with 180 grain and heavier bullets. Such a great powder that it’ll be hard to try IMR 8133 even though I believe it even better.
I use Retumbo in my Nosler M48 rifle chambered in .28 Nosler. The preferred load fuels a 168 grain Nosler AccuBond LR tipped cartridge at well over 3200 fps. I tried force feeding it the same bullet with H1000, H4831, and US869, because that's what I had at the time. It refused to perform. Now it shoots flat and hard hitting sub half inch groups all day long. I tried it in my .30-378 Wby with 180 grain AccuBond bullets, but wasn't impressed. It likes H50BMG much better. Just goes to show you, handloading is the only way to get the maximum use out of the big bangers. Just like a baby, you never know what it's going to like best until you try feeding it different food. I call it the Gerber Theory. [Laffin' 😄]
I've used Retumbo for 7RUM, 7SAUM, and 7 Rem Mag. 7RUM is pushing a 140 TSX at 3623 fps and .625 MOA. Need a strong bullet at those speeds. I have a Boyd's laminate thumb hole stock on the 7RUM to help minimize the recoil with no break.
I'm going to be using retumbo in 7 rem. Mag. Currently using reloader 19 154 gr. sst With fantastic results, 3100 fps. with micharge 1 moa at 154 yds. out of a rem. 700 bdl. hunting rifle with 4x16x50 34mm arken scope

Rem700 sendero
I love my magnums, but as an eastern deer hunter during a component shortage, it's hard to justify shooting them over the smaller or more intermediate cartridges. All that said, I really enjoy my 7 mag, and I my just have to try some Retumbo in it.
Excellent video. I am a new entry into the quarter bores, and so far am loving it!! Do you have any suggestions for load workups for .257 Wby? I have tons of published H1000 data, but cannot find anything using Retumbo. I'm shooting 115gr Berger VLD hunting over 64.0grs of RL-22 currently and would love to see what kind of results I could get with Retumbo to go along with its insensitivity to temperature.
Excellent vid & review. I have only recently used Retumbo because I wasn't able to get H1000 for my 7mmRemMag. I am pleased & impressed with my load development & results. I have only used it with 162g. ELDX. Excellent groups & decent SDs. I have an interesting question for you gents. Over the years I have consistently observed H1000 apparently "heating" up barrel quite quickly. It is noticably heating up faster than the 4350 & 4831 powders I have used mostly. Accuracy seemed to be hindered after 4 shots with most charges. Retumbo surprised me. My 2nd 5 shot groups were as good or better than the first. That has not been the case(for me) with H1000. I need to give the barrel a good bit of time to cool after first 5 shot group if I want follow groups to stay consistent & tighter. Any thoughts or suggestions? Well done men. Thank you.
🤦♂️ Saw this on the shelf at my local store over the weekend and it never dawned on me that I could use it for my 7mm RM. I did get some H1000 though, and I'll keep an eye out for it next time.
Never used it because I can’t get any. The powder that I’m can get is Accurate MagPro for my 338 Lapua Magnum. I’m shooting a 285 grs. Hornady ELD MATCH bullet and Cutting Edge 277 grs. MTAC
Just picked up an 8lb jug of retumbo for the first time today. Hoping to try it in my Winchester model 70 300 Weatherby. 210 grain accubonds and 210grain Berger VLD!
@@mattr9611 Keep an eye and sign up for the emails from Bruno shooters supply out of AZ, thry constantly put up powder for sale, the good stuff goes by fast but that's how I've been staying stocked yhe past couple of years.
I am using Retumbo in a couple of 338 Lapua's I have, both with 93.5 grains. One rifle with 300 grain Berger Elite Hunters going 2835 fps, kills moose dead from a long ways away and close as well, ask me how I know. lol. The other rifle shoots the Hornady 285 ELD-M at 2866 fps. and is also crazy accurate.
I use retumbo in 300 win mag with 220 grain sierra match kings. I bought a pound on a whim about 2 years ago and haven’t looked back since. I previously used H1000 and have been getting much better results with tumbo.
I’ve used reloder 22 as well in my 7 mag for years and get excellent accuracy at about 3040-3050 fps with 162 eld-x. Reloder 26 is my go to powder now for my 7 mag though because I’m getting right at 3200 fps with the same bullets and my accuracy is still excellent. I’ve used retumbo for my 7 as well and actually got the best velocity out of it compared to any other powder I’ve used. However, the accuracy wasn’t there in my rifle so that’s why I stick with reloder 26 & 22.
@@matrix5175 re26 is like magic velocity powder!!! A friend uses it in a couple calibers to down right insane velocities!!! I have not seen any to try.
@@GripEngineering I just got into shooting about 1.5 years ago, so it is the only magnum powder I have experience with. I have nothing to compare it to. I will tell you that I love how easy it is to measure and work with in general.
Why not get a muzzle brake? Large magnums really benefit from a brake more than other cartridges. You can get up to 60% recoil reduction if you choose the right brake. All brakes are not equal, so you need to do some research.
Once I’m out of factory ammo, gonna work up a load for my 7RM using this powder. Sierra has good load data using their 160 grain GameKing HP. Assuming it groups well, should be devastating on PA whitetails at just about any range.
In my 300RUM, I run 92gr of Retumbo with Norma brass, and Fed 215m, pushing a 200gr Accubond 3145fps with stellar accuracy, like .25 moa. This is from a 26” barreled Fierce Fury. It is an elk hammer.

Im wondering the same thing. I just bought some Ramshot Magnum to try in my 257 Weatherby
Teasing us with all of these powder reviews….
Enjoyed video on Retumbo. Could only get one pounder, but grabbed 8lb of RL26.
Where in the world did you find RL26?
Where???
I shoot a 300 RUM Sendero with 180 grain Sierra Game Kings shooting 99.5 grains Retumbo at 3375 FPS. (Kicks like a mule)
Excellent vid & review. I have only recently used Retumbo because I wasn't able to get H1000 for my 7mmRemMag. I am pleased & impressed with my load development & results. I have only used it with 162g. ELDX. Excellent groups & decent SDs. I have an interesting question for you gents. Over the years I have consistently observed H1000 apparently "heating" up barrel quite quickly. It is noticably heating up faster than the 4350 & 4831 powders I have used mostly. Accuracy seemed to be hindered after 4 shots with most charges.
Retumbo surprised me. My 2nd 5 shot groups were as good or better than the first. That has not been the case(for me) with H1000. I need to give the barrel a good bit of time to cool after first 5 shot group if I want follow groups to stay consistent & tighter. Any thoughts or suggestions? Well done men. Thank you.
🤦♂️ Saw this on the shelf at my local store over the weekend and it never dawned on me that I could use it for my 7mm RM. I did get some H1000 though, and I'll keep an eye out for it next time.
Works awesome through my brother’s 7mmRM!! Best load with a 140 grain Barnes ttsx.
You saw retumbo on the shelf? Go see how much is goin for on gunbroker, like $150 a pound
I’d seriously drive 1000 minutes to buy Retumbo off the shelf. Where in the nine hells did you find it?
@@biggs8729 How close are you to NJ?
@@smalfry83 a lot more than a thousand miles. Thanks anyway
Never used it because I can’t get any. The powder that I’m can get is Accurate MagPro for my 338 Lapua Magnum. I’m shooting a 285 grs. Hornady ELD MATCH bullet and Cutting Edge 277 grs. MTAC
I use it on my 22 SAUM. Love it
Just picked up an 8lb jug of retumbo for the first time today. Hoping to try it in my Winchester model 70 300 Weatherby. 210 grain accubonds and 210grain Berger VLD!
I use it for a 7x375 ruger. It is a great powder.
love retumbo and N570 in 300 norma
I use H 1000 also R 26 for my Mag Bullets.
It would be nice if it was available, the only thing I like better for my 300 Win Mag and 215s is Vihtavouri N570.
Ill have to give this a try, I have such a hard time finding tumbo. N570 is probably tough to find too but gives me a second option.
@@mattr9611 Keep an eye and sign up for the emails from Bruno shooters supply out of AZ, thry constantly put up powder for sale, the good stuff goes by fast but that's how I've been staying stocked yhe past couple of years.
I would like to see everything and anything 300prc. Thanks.
7MM Rem Mag. Always used IMR 4350, then switched to H 4350 when IMR got hard to find. I will certainly try Retumbo when I run low.
How about some 6.8 Western reloading data? Thanks!
I am using Retumbo in a couple of 338 Lapua's I have, both with 93.5 grains. One rifle with 300 grain Berger Elite Hunters going 2835 fps, kills moose dead from a long ways away and close as well, ask me how I know. lol. The other rifle shoots the Hornady 285 ELD-M at 2866 fps. and is also crazy accurate.
I wonder how it will work in a 25 WSSM with a 20 in. Barrel behind a 115 ballistic tip
Use retumbo in my 30-378 Weatherby and it shoots awesome to me 3 shoots under the size of a quarter.
700 Rem Sendero in 300 RUM with 190 and 210 Berger as well as 205 Badlands Precision. 500yds+ and the deer drop in their tracks.
I use retumbo in 300 win mag with 220 grain sierra match kings. I bought a pound on a whim about 2 years ago and haven’t looked back since. I previously used H1000 and have been getting much better results with tumbo.
Retumbo for my .300 RUM with a 180 TTSX going 3220 fps
Retumbo is great with 7mm rem mag, 180 gr berger vld...
retumbo is the rebranded AR2225 i use it in a 300RUM with a 208AMAX and get a 5 fps difference in 10 shots
Another great powder from the Australians, works very well in my 375 Cheytac :)
Yep it's ADI AR2225 here in Oz. Rebadged as retumbo overseas.
I run Retumbo in my 7mm STW with 175gr ABLR @3175 fps
I use H4831 for my 7mm rem mag , but you've given me another option to try.
RE22 is my go to for my 7Maggie. I use the 162 Hornady and 160 Speer 100%. Right @ 3K. MOA accuracy too!
I’ve used reloder 22 as well in my 7 mag for years and get excellent accuracy at about 3040-3050 fps with 162 eld-x. Reloder 26 is my go to powder now for my 7 mag though because I’m getting right at 3200 fps with the same bullets and my accuracy is still excellent. I’ve used retumbo for my 7 as well and actually got the best velocity out of it compared to any other powder I’ve used. However, the accuracy wasn’t there in my rifle so that’s why I stick with reloder 26 & 22.
@@matrix5175 re26 is like magic velocity powder!!! A friend uses it in a couple calibers to down right insane velocities!!! I have not seen any to try.
Haven't tried Retumbo yet. I've been running Reloader 22 in my 6.5 PRC. 52.3 grains with either a 140 Accubond, or Eldm equals sub moa all day long.
The only powders that I have found in local stores are imr 3031 and 50bmg. Nothing else has ever been in stock.
Never in stock though. That is why I am using LRT. It's in stock more often.
How would you describe your experience with LRT?
@@GripEngineering I just got into shooting about 1.5 years ago, so it is the only magnum powder I have experience with. I have nothing to compare it to. I will tell you that I love how easy it is to measure and work with in general.
Been using it for my Sako 75 Hunter 26" barrel 300 RUM for a long time!! Nosler 200gr Partition with 93gr Retumbo. Hard on the shoulder!
Why not get a muzzle brake? Large magnums really benefit from a brake more than other cartridges. You can get up to 60% recoil reduction if you choose the right brake. All brakes are not equal, so you need to do some research.
Wish I could find some
Would be nice to actually find some in stock
Also 338 Lapua with 300 Bergers.
Once I’m out of factory ammo, gonna work up a load for my 7RM using this powder. Sierra has good load data using their 160 grain GameKing HP. Assuming it groups well, should be devastating on PA whitetails at just about any range.
I use Retumbo for 375 CheyTac. I am an ELR competition shooter and I'm spitting out 361gr monolithic bullets out at 3100 fps. SD of 4.
How can I get in touch with you?
weatherby Mark V 7mm rem mag 26" Bartlein barrel 72.2 gr Retumbo 180gr ELDM @3100fps
Like it for my 264 mag best accuracy with 140sst at just over 3000 fps less than 3/4in
Retumbo works good for the 28 NOSLER, 195 Berger EOLs. Retumbo, H1000 have good burn rates for that combo.
