Ballistic & Conversion Calcs
Sold & shipped by Pyramyd AIR
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.

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 changed:The 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 know:Shoot 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 know:I've tested 9 different brands and weight slugs over the past 5 years and these are by far the very best from my Armada!

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 changed:I 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 know:If 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.
