Outstanding overview of proper shooting and Ballistic dynamics. Thank you !

I have a friend who is an ex-military precision shooting instructor. This guy owns 300+ scoped rifles and is constantly shooting a variety of calibers at over 1,500-yards. I asked him what his thoughts were about the Barrett MRAD and MRAD-SMR in .300 Norma Magnum. He said that he had one and sold it because it could not shoot better than an inch at 100-yards, and more like 1.25" - 1.50" inches at best. He said that he had a number of friends who had the same experience. He said that the 1:8" twist on the MRAD was just too fast for the 220 to 250-grain bullets like the Hornady A-tip and extreme distances. He said that he a SAKO TRG-42 that he rebarreled with a Bartlein 28" barrel in 1:9" twist and he can engage targets past 2,500-yards with it. Does anyone have any thoughts based upon experience with this rifle, caliber, and the 1:8" twist rate? Does the MRAD and MRAD-SMR in .300 Norma Magnum have accuracy issues when shooting out to 2,000+-yards? Thanks

Very helpful… thanks

How about the establishment of a custom shop willing to build barrels chambered in the cartridges and to the specifications we want.

I don't want to sound negative, but did you have any misses at the mile and 2K and not included in the video? Either way you are my inspiration for my upcoming 300 NM

Yep look at the Central Limit Theory

Just discovered your channel interested to see another Australian working on an interesting case

I thought Australian were allowed to own guns period but I guess I’m wrong good to see you guys still have some

Nice video. Hand loads and some guns like a particular flavour of bullet. I've found speer 150gn spbt to work very well in all my 30 cal guns even my Ruger precision in 308 like them and I can shoot coke cans at 250-300 meteors all day long makes a good hunting rifle for long distance head shots

Seeing those AR's enjoying the aussie bush makes me sad. We used to be a real country, where people could buy what they wanted, when they wanted, just because they could. Now they're (essentially) banned, like everything else that's fun in this country. Bad eating habits kills more Australians every week then AR's would in a hundred years. I dream of moving to some American country town and just enjoying life, without worrying what the government will come for next.

I couldn't be happier with my LA101! It's a laser.

A broken clock is right twice a day! I like his proverb and will be using it from now on :)

Great trip with some mates, shame about the pigs. Hope you've had better luck since.

Good on ya, Ben.

I have a LA105 in 6,5CM , after approximately 500rounds I had a few issues, the action front bedding screw came loose and only had 3 threads purchasing into the action. The rear bedding screw goes into a dovetailed nut in the rear action tang, this was also loose allowing the action to move side to side whilst firing causing split groups. As I am a fitter machinist I have the skillset to remedy this, but why isn't it built better in the first place! Also the locking lugs had to be deburred and trued! Shoots fine now. 10mm groups with reloads.

Remanufactured Lithgow no1 mk3 & or mk3* rifles would sell more then any of these modern rifles . Parts kits for existing rifles & accessories are another avenue. Hunting & patrol type rifles or any modular configuration is possible on that platform. Wrist adapter for AR buffer tubes / stocks & pistol grips . The sky’s the limit with options to the forend . Dream it build it . The Indian ishapore no1 mk3* rifles were made with a better steel & heat treatment ( back in the 1960’s ) & chambered in 7.62 nato . As if stronger one’s couldn’t be made today & chambered in 223 , 6.5 creedmoor, 308 or some of the short magnums . With mim & investment casting techniques, polymer stocks , laminated & carbon fibre stocks there’s a rifle for almost everyone. The ELR market is relatively small A no1 mk6 1/1 is just about perfect for most hunting scenarios, it crosses over the Jungle Carbine , patrol rifle , hunting rifle, service match rifle roll perfectly. Rear mounted flip up peep sight , charger / stripper clip fed , 10 rnd mag , red dot or forward mounted scout scope . Or over the action scope if preferred. Just my opinion. Probably everyone I know would buy at least one !

I think the 102 did a very admirable job considering both chassis rifles were fitted with brakes and shot off an Atlas. Nice work Lithgow 👍

I would say this is more of a Armalite AR-18 that a AR-15. It looks very similiar to a BRN-180, which was built off the AR-18 design. :)

It's good to see that we are making them here. I think we need to change those gun laws of ours as well...

Every day a new adventure. Reloading for about 12 months, I’m a novice, but continue to up my reloading game. However, consistency continues to elude me. To limit environmental effects, most of my testing is 100 y. indoor. I use the same lot of bullets, brass (where I can), primers & powder. Dies are from RCBS to Redding, Forster and even Micron. While I don’t sort bullets (yet) or use an arbor press, I try to make upgrades that give me the most return for the time and money. I’ve even tried turning necks where I cannot find premium brass. I reweigh every hand load for consistency. Each additional investment adds very little if any reduction in ES or SD. Some days the SD is single digit the next it’s 17 to 27!? Lately I’ve pulled the trigger (pun) on an AutoTrickler v4 to step up my charging . Shooting/reloading 204 (Cooper), 243 (Custom), 6.5 CM (Ruger RPR) and 7 PRC (Custom), my hand loads present tighter groups than factory, but factory SD are almost always much lower. That said, any thoughts on what I’m missing….. skill set, technique, equipment???? Thanks.

So should the smallest groups always have the lowest velocity SD?? Mine typically do not. Would you choose charge and seating results based on SD alone?

Very sharp ,really nice looking setup 👌 congrats on the setup

I keep watching videos talking about 'Mean Radius' but nobody explains how to measure it.

What’s next

Tikka is pronounced "Tea-ka", not "Ticker". Other than that, good review.

I don’t even have a 375 Cheytac ( yet ) but subscribed purely because your editing kills me!

Im busy buying this exact setup :)

WT-25, I stupidly bought two of them. Now I know where the 25 comes from. You only spend 25 percent of the time shooting them, the rest of the time you spend sorting out stoppages. Don’t waste your $

This ought to be a series, love people stretching the distance on 22 lr

Good video! It's great to see a little bit of statistical reality in the shooting world for a change :). One issue to consider: you say at 9:58 that mean radius does not need to be scaled like ES does. No disrespect intended to Mr Litz, but this is incorrect. The MR of any given group of size n will always underestimate the "true" mean radius of the underlying distribution -- this is due to the fact that the MR of the individual groups are calculated from the center of the group, not the true center of the distribution (which will always be further from the observed points of impact than the center of the observed group). In other words, the mean radius of an n-shot group is a biased estimate of the mean radius of the underlying distribution. And just like the ES, the bias gets smaller as n gets larger. I'm also skeptical of the idea that you can simply multiply MR by 2.1 to get the 95% probability area. It's been well-established in statistical theory that you can multiply the Circular Error Probable of the underlying distribution by 2.1 to get the 95% confidence area. But 1) the CEP is not the same as the MR and, 2) more importantly, we don't know the CEP of the underlying distribution. All we know is that the MR of a given group underestimates the true MR. That gripe notwithstanding, the method that you lay out is WAY more reliable than the common ES methods. Thanks!

I'm in st Martin a island in the Caribbean

I have a tikka t3x super varmint 223 it shoots norma bullets extra good (5 shots in one hold at 60 metters ) try normain your gun

Good stuff! The visual explanation of the 2 shooters and their subsequent shots made the concept click into place for me.

Wow ! Quality

What a good review. I'm glad I saw it because I was just about to buy a Howa 22-250 Varmint but after seeing another review on here I wasn't happy with the accuracy. I ended up copying you exactly with the stock, barrel, twist and scope. I didn't worry about the bipod because I only shoot off the back verandah, I set up a Caldwell rest on the back table to occasionally shoot a hare or rabbit just over 200 metres away. They tend to pop up on the edge of a dam and fence line own there. I live just out of Gloucester in NSW. I couldn't be bothered walking or driving around looking for game these days. I sighted it in to hit dead on at 100 metres and I find that if I hold on the upper centre of a varmint at 200 metres the bullet doesn't seem to drop at all. I never take the scope off 15 power. I would't mind getting a bit more technical with the scope so I might go on the Burris website one day like you suggested. Thanks for a great review.

Can i export data from this app (range card) to exel? I have kestrel but I need to print this data and use fully analog :)

I hate you!!! JUST A JOKE! lmao After watching this it makes me even question building a 300 prc. My objective is long range as well and 300 norma mag just seems to have better numbers. So thanks for this! I mean I can have both just a simple barrel swap but better to have 300 norma mag for numbers but also because I'm prior service US Army and they're adopting this round as well.

4 impacts at 2k. Out of how many shots tried? Great shooting at any rate!

Nice set up & good shooting...but I think you failed in your objective here. You selected .300 NM on the basis of a calculated hit rate of 29.7% on a torso target at 2k- compared to a 21.4% hit rate using .338 LM. Did you achieve it, matching theoretical to practical outcomes?

Farmers should be able to own this.

Loved the video. Subscribed.

Great video thanks Can this mobile app link with Vortex Fury?

Get rid of the music

Here in Canada and the US, ES-extreme spread is calculated using a chronograph. Taking the fastest speed of your five, ten shots and subtract the slowest speed of the same five or ten shot groups. The best I can get so far is 20 fps between five shots.

This video settles it. My next rifle caliber will be .300 Norma magnum, not .338 Lapua magnum. And the company to buy from will most likely be Accuracy International.

The sound barrier causing 22 bullets to lose stability and accuracy is a myth, there's a video of a guy who shot groups with sk high velocity match ammo along side groups with sk rifles match ( subsonic velocity ammo) at 50 yards then again and 100 yards and the groups didn't change much matter of fact at 100 yards the high velocity ammo had better groups at a 100 even though the sk rifle match subsonic ammo had slightly better groups at 50, so yeah it's a myth guys use your high velocity 22lr ammo, especially for hunting it's packs a harder punch down range and dispatch game cleaner

Out of curiosity where does the 2.1 value come from?

Grate rifle. 😊

This was a really great video mate … production quality came along way from a few years back ✅💪
