This is exactly my experience! If you are using a Superior standard barrel, you need a JSB .216 slug. You get the same tight spread at 50m! The ideal speed will be between 920-940fps. (700mm barrel 125bar reg press) If you are using a Superior Heavy Liner barrel, you will need a .217 slug. JSB is an extremely accurate projectile. But extremely sensitive to the correct velocity and caliber. You may get a lot of flyers. JSB KO is made of very soft lead, you have to be careful not to damage it. Also, it is worth cleaning, Superior barrels like it dry.
I love these slugs in 216. They are a bit slow to open with pigeons and seem to work best at 960fps in my older 600mm slug barrel. I can reach out to 100m no problems.
Jsb out of superior heavy liner.22 group very well even at 990FPS and my Fx impact I tuned them to shoots @994fps and at 41M it goes to same hole /slugs on slugs. Well done
Superiro heavy is 1:16. The superior heavy is only required if you want to shoot above 30gr slugs, but I do believe the faster twist rate to be better, I shoot anything from 22gr up to 30gr with this barrel (and pellets) with great accuracy.
Hi Gert great content again mate keep it up , Quick question I am getting a Fx imp M3 but unsure at the Moment as to get .22 calibre or .25 usage small game and targets up to 200 yards any advice would be much appreciated thank you..
I am not familiar with the .25 as it is not available in SOuth Africa due to stupid gun laws. The .22 is the most common calibre and for that reason you get the biggest variety of pellets and slugs, not much difference in knocking power between the .22 and .25. Availability of ammo and choice of ammo must be a deciding factor. The 22 with a 30gr or 34gr slugs can bring down just about anything.
@@AimSmall Hi Gert thanks for getting back you are right definitely more choice in pellets Ect over here for the .22 but I think .25 shoots the slugs better in just the standard form ..
They are just to expensive in my Country, even if they work well I can't afford to shoot them. 3 times more expensive than any other brand and not readily available.
oh oh amazing! i never shoot well with this slug and my m3!. what is your reg setting? my m3 is 700mm standard barrel. i hope see one day good group with jsb slug
@@rayman1366 That is very weird, just shows that each barrel is different. Remember that slugs can be extremely speed sensitive, by adjusting the speed as little as 5 fps can have a big influance on groupings. Next time you do groupings, try closing the adjuster valve in front of the gun with a quarter turn, it might just improve your groupings.
I was wondering if you have tried the FX 25.4 grain that appear to be identical to the JSB redesigns? I have recently purchased a Daystate Red Wolf .22 HP and it shoots most things great at 40-50 yards but 75-80 yards the Redesigns are easily king and I wouldn't really want to use anything else if the shot counted. I have tried 2 different style slugs and neither have grouped well even at short range, 5" groups at 75 yards. The redesigns stay within an inch. The pellet availability is awful in the states and the Redesigns are nowhere to be found but I have come across the FX that look the same. I envy how many different choices the FX will shoot, I still have a ton of testing to do but it's not easy with the lack of availability and I'm already stuck with a bunch of duds.
Slugs are senstivie little buggers, and will probably need some fine tuning, a 5fps can make a world of difference. In the states have good slugs at decent prices, try NSA in a lighter weight, slugs tend to love greater speed. I also have great success with the Redesigned's, brilliant pellet up to 75m.
@@AimSmall Ok I appreciate that info, the Red Wolf is tunable, I just cant find a programmer available right now. I didn't realize such a minor change would make that much difference. I've never really tried to take a pellet gun past 40 yards before getting the Daystate. This is all new territory for me and that's why I appreciate your channel so much. You have a ton of relevant content. I wish you were using the Redwolf but I'm inclined to say you'd be happier with what you have. I will try the lighter slugs, I've tried 23 grain and 25. Thanks for the tips.
@@ravenshield7823 What you can also try that is a lot cheaper is to lube the slugs a bit, it also changes speed and ,ight group differently, silicon spray is an option, very lightly and shoot about 10 for the barrel to settle...

Nice info, thank for sharing. Will have a try at it in different liners again
I told you knockouts are not bad 😉😁👍.Waiting for the 100 m group with the knockouts !
Gert, you are becoming my favorite youtube subscription. Very enjoyable to watch, keep it up.
Amazing accuracy.
Very impressive.

Really enjoy your vids mate, great presentation with lots of info. Keep them coming
WOW
wowwwww nice....wyting next moreeeee meters...
Great shooting
Amazing accuracy
Only if i can make mine mk2 half of this
MK2 out of the box, depending on liner. Old STX should shoot JSB KO's fairly well, they also love the H&N's in 27gr.
@@AimSmall i have the superior pellet liner in 700mm had shot them from 930 to 990 and won't group. Both in 216 and 217
@@rizojehan Mmm pellet liner doesn't like high speed so much, try and shoot it slower at 870fps. I got good groupings at 860fps.
Thanks

Leke Gert jou doring! Daai .217's maak diesele in my geweer, alhoewel ek geen verstellings het nie. Baie Stadig 780f/s maar n 1 gat groepering op 30m.
* Jsb 217👌👌

Hey sir have you try the nsa slugs?

Hi Gert. What upgrades did you do on your fx? Thanks
Hi werner. Not much, Dual Airflow en Pinprobe, ups the total speed by about 60fps.
SuperB
oh oh amazing! i never shoot well with this slug and my m3!. what is your reg setting? my m3 is 700mm standard barrel. i hope see one day good group with jsb slug
If you shoot the JSB 216 in the pellet liner and older slug liner it should work, or the 217 with the heavy superior liner
@@AimSmall for me i tested 216 and 217 both not worked on m3. just nsa 28gr work well . about 1 cm group 40 meter
