Any info about the JSB KNOCKOUT Slugs in .22 thats not related to FX Barrels ?

[airgun14]

Trying to find some more info about the JSB KNOCKOUT Slugs in .22 that is not related to FX STX barrels, especially the slugliners.

and yes I know, each gun like different pellets, but in general there is a big chance of predicting a gun that like a certain kind of pellet, and in this case the jsb knockout slugs in .22, watched all tube videos, and only find this interesting: Daystate Red Wolf HP HILITE that shoots these slugs good with slow speed,

dont have any clue what barrel is inside that particular gun. And that gun is probably very expensive 

* Is the chance big of these slugs perform OK in Hatsan LW or Artemis/SPA barrels? 

reason asking is I have come over 30 tines of these slugs, and yes I can sell them probably, but it would be more fun picking a pcp gun that probably would shoot them OK.

I cant afford a FX Dreamline with STX barrel, I am almost certain I want a Hatsan BT65 with LW barrel or a Artemis(SPA) M22 (same as M10/M11) anyway, so it would be good if theses where good candidates possible.

I think the recommended diameter for slugs in the Red Wolf barrel is .217", the JSB slugs are .216".

 

[airgun14]

What size recommended slug for Hatsan LW barrel ?

I have shot a few thousand knockouts I got from airgun-haven , they shoot great in MY cricket CZ my ed-guns , and my Taipan regular and my unchoked slug barrel , they shoot fine here and stable out 200 yards , I have shot them in 750fps to 1100fps I like them , just wished they made heavier ones LOU

Lou, Have you tested expansion / terminal performance on the Knockouts? Just curious if they expand.

I totally agree! I've never had a negative encounter with an orange, or any other citrus fruit that made me feel I had to fire in self defense! If any fruit makes you that nervous, stay out of the orchard!!!

 

[airgun14]

would be nice to hear of any Hatsan LW BT65 or Artemis M22/M10/M11 owner that have tried these..

This is the guns I want to buy anyway. well ...... maybee the answer is (at least for the BT65 with LW barrel) what dimension slugs LW .22 barrels like ?

This is Quick five shoots group at 40y with my Vulcan 2. When I saw your post I decided I must try them in my Vulcan. I bumped the speed up to max with hammer spring and this is pushing them on average 780fps.I was shooting in Woods with very bad visibility and 9x cheap scope. This is the result. I know it could be even better. Regards Marko

Thanks to jwrabbit for getting some into my hands. They shoot fine. I shot them out of my R5M at 50fpe. I still have to do more testing to see if I will switch over, but they are definitely worth buying when you get your hands on them.

Nice, seems to shoot very good, even at lower speed, thats a CZ barrel right? what twistrate 

 

[PopEye99]

I understand you frustration. I've been searching as mad as well.
All I seem to find is FX barrels and slugliners, and IF I find something interesting, they've been shooting at 10 or 30m.

I just got the slugs this evening, didn't set up the scope as i'm testing more slugs this weeked.
A quick test, under 50mm/2" @ 80m. Around 80-90mm on my small plinking saucepan lid @ 130m/140y.

It retains energy very well, see the saucepan lid.

I'll get back with some more information after this weekend.



Hatsan BT65RB QE LW barrel choked, twistrate 1:17.7, Huma regulator @140bar, 244m/s / 800fps, JSB KO 25.39gr .216 ~50joule / 37 ft-lb
I'm fitting a larger plenum as soon as I get it (plenum for .25 regulator).

Cheers,

Pop

Kral Puncher (53 cm barrel) likes them too. Very first few shots out of this new unregulated gun. In windy conditions, and at low speed. (720 ft/sec).

Not sure how much it helps but I just tried some 216 Knockouts in my Uragan the other day. At 846fps I was getting 1-.75in groups at 50yd. Just got some 217s in to try them as well. I'm tempted to turn up the power to get some more speed but JSB RDs work so well for me now it's hard to justify.

Here's a link to a thread I posted last month shooting the JSB Knockouts in both .216 and .217 out of my Brocock sniper HP. It does have a LW polygonal barrel. 

 

[bubblerboy64]

The 217. work great in my impact. I ordered some 216 which didn’t show me much in the impact but they do shoot pretty well in my red wolf standard (not HP) gun.
My experience with slugs has been pretty mixed. The are fussy. The impact guns are tunable. Generally slugs seem to like being shot at pretty high velocities and a few FPS can make a difference I found after some considerable expense if you velocity and harmonic tune the impact gun you can trick it into shooting great. If you can not tune the rifle about the best you can do is to buy a bunch of slugs and hope you can find a good match to your gun. Sometimes you can and sometimes not. If you are not shooting beyond 75 yards it probably not worth the trouble.

Umarex gauntlet didnt mind them at 50 yards for a hunting group. Didnt like them at 75, I'm thinking they destabilized. They shot at 720fps. (note these were shot back in september) 

 

[GeronimoKY]

Work great for me in two different BSA barrels. The fx slugs are as good or better in them as well. One can push them a little past 900 fps and accuracy remains the same. Also work well in a custom 2240 hpa with cut by me 16" crosman barrel out to 30 yards but can't push fast enough for my wants. 

 

[PopEye99]

Sorry for late reply.
Nothing wrong with the accuracy on the .216, but they want fall out of the magazine due to the recoil. 
I found out the H&N .217 25gr worked even better (see picture, zero 100m/109yd, 265m/s / 870FPS).

Now with the result above (thanks dreamweaver) with the JSB KO.217 I'm going to try them out too, even though I don't have polygon LW barrel.

Cheers

I’m shooting the Brocock commander xr 24” barrel ploy LW barrel average 876 while it shoots JSB .217 in 25.39 pellets great the KO .217 / 25.39 is shooting sub moa at 100 yds. I shot a squirrel at 100yds in the eye my aim point and another in the shoulder at 100 yds with no pass through both dropped like a stone. My red dots are 1/4 in. I’m amazed after hearing LE don’t do well with slugs. Go figure picture is 15 shots at 100 yards JSB KO 217 in 25.39gr
