Description
These JSB Match Diabolo KnockOut Slugs MKII feature a new flared skirt shape to enhance the performance of what were already some of the top pellets available. They deliver superior power and accuracy with a variety of airguns, as well as excellent energy transfer and expansion on impact.
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.

5 of 5 JSB KnockOut Slugs MKII .25 Reviews
Accurate. My second review of this slug, this time in my FX Impact M3. Tried 9 different slugs, lighter as i want to use my Standard Superior Liner, not the slug liner and all were a bust. Tried these last (10th different slug) and great accuracy at 50 yards, 10 shots under a nickel.
Things I Would Have ChangedThe weight discrepency. They vary up to 1.5 grains but doesnt seem to make a huge difference as accurate straight from the tin.
What Others Should KnowShoot them above 900 fps. Shot them in my Impact at first with my pellet tune and thet were moving 880 fps, accuracy decent. Upped my Regulator a bit, got them to 940fps and a laser, hit right where i aimed at 50 yards. More accuracy testing to come @100 yards.
Extremely accurate!!! Minimal impact shift from my Diablo pellets
What Others Should KnowI've tested 9 different brands and weight slugs over the past 5 years and these are by far the very best from my Armada!
Good weight for a .25 slug, not too heavy nor too light. Good velocity out of my Daystate Red Wolf Safari at 935 fps for 65 fpe. Accuracy is outstanding with sub MOA at 100 yards easily attainable (without wind). By far the best slug I have shot in my Safari and have tried countless others.
Things I Would Have ChangedWeight disparagy. The tins I have had go from high 32 grain to just over 34 grain so this is a 1.5 grain weight difference in each tin I've checked. Will say I've shot sub MOA at 100 yards with slugs pulled straight from the tin however.
What Others Should KnowIf your PCP has good power and can move these over 900 fps I'd give them a try. FYI I've shot them on medium power in my Safari at 840 fps and groups opened up quite a bit. So (I'm guessing) over 900 fps is a good start.
The look of them and the potential they have
Things I Would Have ChangedMaybe price...they're expensive
What Others Should KnowYou definitely need a barrel that likes slugs to shoot these with accuracy. You also need the power to push them in the high 800's to mid 900's..I, myself tried them in my SamYang Sumatra 2500 and although it definitely has the power it didn't like them....Not the slugs fault...This line of air rifle just doesn't shoot these slugs well...

Performance in my various PCPs. Bought a BRK Ghost recently and ALL slugs i tried (13 different kinds and weights) were a bust. Than last but not least..this KO MK2 slug. Laser at 20 yards, one hole than backed up to 50 yards and 5 shots under a nickel.
Things I Would Have ChangedI gave it 5 stars for value but maybe 200 slugs for $20 instead of 150. Also the weight of these slugs is not spot on, they vary up to 1.5 grains in the same tin. Doesnt seem to affect accuracy however.
What Others Should KnowIf your PCP has good power DEFINITELY try these
My Ghost on MAX Hammer spring moves these 960 fps for just under 70 fpe. My Safari, Impact and Ghost all laser this slug.
