Tested: Best FX Barrels for JSB Knock-Out .25

All shots at 100 yards using my FX Impact MK2 @1000fps. This is not a paid advertisement, but the supplies were free. JSB supplied me with the ammo at no cost. FXUSA supplied me with the barrel liners at no cost.

[@KEOutdoors]

I dont even own a FX and still watch all of these videos all the way though with complete attention. Very interesting!!!

Ted it’s during a pandemic brushing your hair is not required You did shave so you’re not completely lazy😂😂

[@joshuagibson2520]

Ted, I'm a firm believer in the old way of just trying different projectiles. I've seen too many times where even 2 barrels made side by side will prefer different projectiles. I understand you're trying to formulate a good starting point and outline consistencies. I do believe there is a solid relationship to projectile weight vs twist rate and what's compatible \ effective. I believe once that is close it's a matter of what outside diameter of projectile your particular barrel prefers. Please, please, please keep sharing your data. Nothing refutes good science!

Thanks for sharing all the testing with us Ted. I have noticed that the 26 gr FX Hybrid slugs make a cleaner hole in my paper targets at 40 yds than the 34 gr Nielson Dimple nose. Hybrids traveling about 950 fps and the Nielson's about 844. Guess I need to buy some Knockouts now? I do know it's a lot cheaper to shoot the Nielson's than the Hybrids.

Ted; I really appreciate your efforts to sift through the myriad of possibilities to help us find barrels and slugs that might shoot well together. I have one suggestion.

[@mikefoor5162]

Having shot .22 lr no two barrels will shoot exactly the same they may be similar but one will have a sweet spot for certain ammo. Time, trial and error to sort things out but you are giving valid starting points. A variety of weights and diameters in slug packaging maybe a place to start.

[@arenaissanceishman6689]

Thanks for doing the dirty work for us, that would sure require a boat load of money for the average man to achieve

[@fredking9118]

I guess I'd better change barrels and dial in the .25's ? The .22 x 500 mm is so much fun though. Merry Christmas Ted. Great video.

[@mightyjoeyoung1390]

Uneven holes are from unstable projectiles experiencing yaw, from poor or insufficient spin stabilization.

[@thescrawler2]

Wrong twist rate will cause this

[@KC-dx5pf]

All the tears in his target where at 12:00. Yaw is a is a projectile starting to wabble and spiral. Ten shot group would have tears going in different directions. I can’t say what is causing it, and yaw certainly would, but every tear was at the same 12:00 position. Maybe see what it does at 90 yards or 110? Quite interesting.

[@grinchyface]

@@KC-dx5pf This can be true, but airguns are incredibly consistent ( .001% velocity variation in a well tuned gun), and the ammunition is more consistent than your average centerfire factory load- they are generally cold-forged/swaged into their final shape and so the weights are generally sub tenth-grain variance. Due to the (very consistent) harmonics of the gun, you can generally see chains of shots with similar patterns, because the projectile is leaving the barrel in precisely the same manner that it did before and may be carrying several different moments as it flies through the air, one of which could have it nose down or nose up for most of the flight.

[@corny155]

Id like to see what happens if the FPS were increased.

[@fredking9118]

The slugs are great in heavy cross wind. I have aplace on the river. The wind howls . You can hear the smack real well.

[@Powerpickle68]

I tend to think they knew who the rifle was going to. My .25 Maverick compact arrived shooting the kings at 745 fps on max. Adjusted the hammer spring a lot to get those and hades to just under 900, now its right. Other reviewers have theirs arrive shooting slugs in the high 900's.

[@asmrwithkhloe8459]

Ha, I may be one of the few that actually likes the pellet/slug culling process! I have chased Jeff's Crown and finally got my new MK2 Crown .22 to match his....Ha, probably helped I bought it from him and had him set it up but even then it took time to massage everything to get it there...... My other guns, part of the fun is loading up the range bag and getting outside and trial and error.....That feeling when you finally get that MOA group at 100 and the fiddling with this and that to get there.. I have owned EVERY FX gun produced and would not trade all the options today and that process of seeing what works for the days of chambering a 25.39 in my 500 and knowing that was the best ammo period... To your point of a formula.....Throw in the towel. Each barrel no matter who makes it via what process will never be 100% equal. Tiny grooves or imperfections will turn an inch group into a two inch group when it comes to the ammo we shoot. There is a reason why a 175 grain slug out of a big bore is more predictable when shot out of the same brand and make of gun.....Sheer heft absorbs those imperfection better than a 33 grain soft based slug. Find what works for YOU and enjoy it...For God sakes when you do hit the nail on the head LEAVE it be and just savor it!! That being said I have found 600mm is better for me with slugs....NO idea why but I am guessing the interaction with the ammo and the barrel makes all the difference and somehow 600mm gives the best results on the barrel imposing its will on the slug (or pellet)...My findings so take with a grain of salt. Stay well Ted and as always appreciate the detail you put in to each video!

[@nellcreations9044]

Mr Ted.... We miss you man..!

[@royyoung5731]

I just got my 25 cal Maverick sniper Thursday. I put the Element Titan scope on it (your welcome). Nice scope. . I shot for about 1 hr at UA in Orem UT. It is a 30 yrd range. What is interesting is I had the Crown before I got the Maverick and I would get some fliers but the Maverick right out of the box after UA set it all up shot a lot better groups. Four shots less than .2 CC So what I am saying the advancement in the technology on these rifles is amazing and the things you thought you might be doing wrong bad trigger pull, breathing etc. may not have been the problem. It was the equipment had some variables that the new guns don't have. The purchase was well worth the money. c

[@drichards6626dr]

Appreciate the hard work you do to find an accurate combination. I haven’t had much luck with slugs

[@KC-dx5pf]

My money is on your .30 impact! I have worked hard to replicate you and your rifles groups, and have gotten quite good, but no cigar!

[@nmoran2046]

You may not be wrong with the angle of impact on the paper but it may not be the projectile it may be the target if it’s as windy as you say the target could have blown off of 90 to the angle of impact may not be the slug If you could re-create it on a piece of plywood with a hole cut out so the pellets can pass through then yes it’s the slug I believe the range you shoot at uses a construction fence to hang your targets so there’s room for movement just a thought

[@HoldOverVlog]

Great point!!!

[@MAAAH1581]

very good point

[@KC-dx5pf]

Hi Ted, thank you again for sharing your knowledge! I spoke/thanked you after 2017 EBR after I won sport class. I learned from your videos for years! Could it be possible if pellet wabble caused these tears at 100 that the spin and wabble would be at exactly 12:00 position every shot? Seems very unlikely to me. Thanks, and see you in competition soon! I have been on hiatus for a couple years, but coming back now. Thank you again for your knowledge! Whiteout it I could not have done so well in 17!

[@bradleym630]

[@Slipstream28]

I agree with Pelletgunner the pellet is tumbling at 100 yards, this is why you are getting angled wholes instead of a straight punch. I have seen this shotting .308 on paper targets at long distances with light rounds that do not stabilize correctly.

[@eugene590]

new to FX in fact im on back order. .30 Dreamline bottle. ordered the chronny and extra mags/bottles but I will be in way over my head having never had a regulated tune-able gun b4. heyzues that scope is way big must cost as much or more than the gun and add 3 lbs I've Wanted an FX for years because of your videos.

[@georgedeedsnotwords2162]

Great video with great content . This is where a good high speed camera down range might help . To see the position of the projectiles are as they enter the targets . Keep this s@#t coming . One day we will be able to use all this data .

[@pasjooter1039]

The problem with the tears is your bullets are not stabilised enough, I had this with a 243 win in the past, had the same pattern with heavier bullets 100grs, once I dropped down to 85 gr it was shooting like a laser. Basically my twist rate was too slow, don’t know if that’s the case with your barrel. Just started into PCP, not enough experience yet. Nice vid.

[@BionicRusty]

Great point and one that regularly plagues the airgun shooter. My honest opinion is that any variable could cause destabilisation. And it only has to be a small one. I was shooting QYS domed 2 wks ago at the range with winds of 0-4mph. Groupings we’re awful with tears like Ted is showing. Last week, the wind was 10-15mph and with exactly the same set-up, I was 10mm groups at the same distance. (Only 30m but I’m in the UK and that’s my ratting distance). The only variable I can think of to cause the destabilising is the wind. It seems counterintuitive but the QYS pellets are seeming to perform better with some wind. More testing required. 👍

[@hotchihuahua1546]

On the design of the pellet you aren’t just shifting the weight forward on the pellet you are also pushing the pellet into the barrel more or less to the groves of a given barrel , does that make a difference ? So many variables , I feel for you .

[@lancemclean5700]

Hey Ted. Watched a video a while back about powerful new .22 pcp's and new heavy pellets. You noted that perhaps this may be the future for competitive shooting as the BC is getting quite good. I am thinking either a daystate red wolf or Fx crown. I would Love it in .22., as I have a FX Streamline in .25 already. But do you think .25 and .30 are still the choice if you wanted to get into bench rest or extreme bench rest shooting. I noticed a few good shooters using .22 for the one gun challenges but not sure how many would choose them for dedicated bench rifles.

[@airrifleshooter.516]

Malta JSB knockouts still hasn't arrived yet. I have a .25 cal 700mm STX pallet liner A and I am shooting the Barracuda Grizzly in 31 g slugs quite good at 864 to 835 fps . Have you ever tried the Barracuda Grizzly slugs ? Thanks for the tutorial you share with us Mr Biers.

[@fredking9118]

[@richarduk679]

Hi Ted. Was wondering. Do you think that the torque applied to the locknut of the liner system would make any difference to how the gun shoots?

[@HoldOverVlog]

Yikes!! Never even thought of that! Gotta test that at the range next time. 👍

[@reddemon652]

I do belive it could make some difference!

[@christhomas4260]

I have been playing with torque settings and liner rotation.10 to 15 inch pounds works well for me

[@corny155]

Yeah…there are a lot of variables that come into play with the whole liner system. Like say, that 600mm crown barrel that stacks ko .22 mk1’s. What are the chances of getting that liner into another rifle and seeing the data repeat? My guess is…it wouldn’t

[@CDavis-vc8gl]

I was shooting the .25 cal Knockouts this weekend w/DreamLite for the first time and noticed the target tear also. I would like to know what is the cause also.

[@flytelaw1]

Ted, can you put a slo-mo camera at 90 degrees to the poi so you can establish pitch up versus pitch down on the tear drop entries....this will confirm, or clear up any “over/under stabilization” issues. Are you seeing that significant velocities changes are changing the tear patterns or is a particular distance involved......Cheers, Ted, Merry Christmas and don’t let the trolls kill your mojo😎

[@asmrwithkhloe8459]

@10:00 - showing far. Bbls. . . Question: have you ever shot 5mm or .20 vs .177 or .22? Rsn: Sheridan (an old style pump airgun) was avail. late 70s and early 80s. Did not have access to a chrono, but, could get consistent placement in no or light wind at 50yds. No easy attach pastor glass, so, just later peep sights and OTS notch-n-post. Targets were bottle caps and sweetgum tree balls. Better eyes back then. Nowadays the airgun and my eyes don't work so well.

[@spclarryy]

Dude! Awesome video. Thanks for the info. One question, which length of barrel in the .25 cal STX?

[@HoldOverVlog]

All barrels tested in this vid were 700mm.

[@anthonydefillippis8806]

In .22 with the 700mm slug A barrel I’ve been getting phenomenal accuracy using the MK 1 JSB knockouts. I would like to try .218 knockouts because my 600 mm loves .218 . I’ve been trying everything and whatever results I get I try to share on Facebook or the comment section of videos. So far with my experience you must keep testing and like Matt Dubber has said reg pressures play a big role in the accuracy

[@heathhalfhill6867]

It could be the camera shake when the gun was fired, but I swear I saw the slugs corkscrew in flight. Could be an optical illusion, might not be either. Would a corkscrew cause the long tear in the target, or just the pitch of the slug on impact?

[@HoldOverVlog]

On most shots, it is an optical illusion. If you slow the video down, you can see it more clearly. I will likely add a few "super slowmo" shots next time to set everyone's mind at ease. :)

[@josephlopes4477]

Were do I go to see what ammo types work better in the Umarax gauntlet barrel

[@sailingkoko]

Hey ted, been watching you for a few years. Im looking for a super quiet back yard small game gun. Is there a gun with lots of power that wont frighten the neighbors?

[@reddemon652]

Even barrels in center fire cartridges same caliber and twist rate identically the same will have different personalities of wich bullet it shoots best. In my opinion your fx barrels will be the same way. The longer the projectile, the faster the twist rate will need to be to stabilize the bullet in flight. Key holes means to slow a twist.

[@archer1964]

Very very good 😌 very very nice 👍

[@dforr2981]

Regarding tears in target...You didn't tell us where the wind was coming from? Behind then the back of the slug could be pushes down nose up. Thanks for testing these for us Ted. ..as far as the different liners go, how can I tell which is which? And what is the difference between the Superior and Superior Heavy?

[@HoldOverVlog]

The liners are all labeled, either with labeling tape or sharpie. Wind was from the right (south). Superior Heavy barrel is more aggressive than the Superior. Faster twist rate, and possibly more choke (memory fails me).

[@etiredevill7834]

Hello Ted, I have a few liners, one of them from a Dubber slugger. It only seems to shoot JSB Monster redesigned. What I wanted to ask is, have you noticed different rifling depth on your barrel liners? I have .25 Superior liner, and the land marks when you push a pellet are quite pronounced. The land marks when pushed through the Dubber slugger liner (which I thought to be a superior heavy liner) are almost non-existent. If you have barrels such as described, do you find the longer / heavier slugs don't perform in the "light" rifling?

[@SorenDrost]

My experience with slugs coming in "tilted", you need to either go up or down in velocity 👍🙂

[@Acutus3399]

I was thinking down. I feel FX is trying to get thinks to work in the 900ish range. I definitely try myself with my new Maverick

[@XM913CG]

Was about 55° with sun. Yesterday same range same everything. Group was closer to an inch. All this was at 50 yes. ES 4 SD 1.5. Group was not as good a chrony showed. Colder air in more dense.

The angle of the projectile is hitting the target at a different angle

[@jonhewitt3]

I always thought that when the pellet wobbled it didn't have a clean hole within the target, hence the tear

[@allanwind295]

Wouldn't you expect a wobble to be tearing in all 360 degrees? The paper all show a tear right above the main hole with maybe 10 degrees of variation like at 1:16. The theory of it coming in at a arc and edge of the hollow point grabs the paper on the way down makes sense to me. It's not consistent, though, like at 11:58. How does does back of the paper look? Is the paper split or missing at the tear?

You talk about the barrel a lot, but i didnt hear you mention the fact, jsb dont always make the amminition 100% correct or that they might miss label the tin.this does happen here in the uk or so it seems.did you check the size and weight, 100yds shots, every little counts

[@tripleceas]

Dreamline .25 600mm Superior Liner. Stacking NSA 29.0’s all day. Still not 100% but I believe the Huma pin probe made a significant difference in accuracy for me, not because of velocity but because it seats 10 thousandths deeper than the factory probe. That’s my theory anyway. I only shoot the NSA 29.0 out of my dreamline anymore. At least until I get an impact or a Maverick.
