Always be mindful of what is beyond and around your target. Because of their high BC, slugs will carry more energy further downrange than pellets. Make sure that your shooting area is safe and that you have a sufficient backstop in place when shooting these projectiles.

10 of 10 JSB KnockOut Slugs .216 Cal .22 (5.5mm) Cal Reviews
They all seem to be consistent in weight
Things I Would Have ChangedBigger containers with more in them
Great first impression, they shoot one ragged hole @ 25y out of my MFR. Chronnyed @ 642-646 FPS on a 24 shot string, yielding 23-20 FPE over a range up to 50y. I like 'em.
Things I Would Have ChangedLess shipping cost.
What Others Should KnowThey fit tighter.
accuracy : 5 shots gave a 3/8 inch group at 45 yds. The .216 grouped better than the ,217 KnockOuts (1/2 inch group) in my Flash Pup. Energy: 10 shot average of 38.66 ft-lbs
Things I Would Have ChangedHave not shot enough. Saving for Spring varmints. Always nice to have lower cost.
What Others Should KnowToo heavey for my .22 Gauntlet and my Regulated Hatsan AT44S QE. The AT44 produced an av 5 shot energy of 21.26 ft-lbs while the FlashPup generated a 10 shot av energy of 38.66 ft-lbs.
Great pellets. Good weight, fantastic down range thump. My 1322 loves them.
Things I Would Have ChangedNothing!
What Others Should KnowTry them out I believe you will love them.
Hits hard, accurate.
Things I Would Have ChangedMake a more fuller size to fit the sumatra magazines, they fall through, so you have to load them and hold your hand under or over the mags until you load them in the gun.
What Others Should Know975 FPS in my neutron star and 825 in the avenger and they shoot very accurate. Will turn up the avenger to maybe 880 FPS and see how they shoot at that speed in that gun. Will tear the back side out of crows with a chest shot
GREAT FOR HUNTING! GREAT ACCURACY, GREAT PRICE!
Things I Would Have ChangedDelivery took longer than I expected.
I just fired about 50 of these from my Crown, with a 500mm barrel with slug liner. I got 950 fps at 50 FPE. I tested these at 35 yards. I got one hole groups with two pulls or flyers. I'll try the .217 as soon as they get them. These are very accurate, likely good at over 100 yards. GREAT slugs from JSB !!! Nice screw tins. I fired one at a block of duct seal. Perfect expansion. Again, great slugs. I believe they claim a BC of .08 ? I'll test for BC when it ain't raining.
Things I Would Have ChangedI am very pleased as they came.
What Others Should KnowThese require a powerful weapon. Great slugs.
I bought these for: weight and underbore size(.216) . The size give a fair fit ( less friction..more fps) in my 27 ftlb springer. Mach 12.5. The weight at greater velocity gives better range and knockdown than my usual max load of Rabbit 2s...however less hardtarget penetration at all ranges.
Things I Would Have ChangedThey will fall through most .22 cal. Barrels at .216.. I lost one for a while in my Benji Prowler suppressor. If you have a tight barrel..as 2 of my guns do..then they perform acceptably. 17 foot pounds is about minimum to push these with workable results.
What Others Should KnowA GOOD Supermagnum springer ala hatsan 125 could headshot fatally any legitimate smallbore game easily with these. I do coyote. Fox.raccoon.possum.medium pigs.waterfowl. jackrabbit.javelina.etc.i have nobpcp gons...so no results to report on that platform
