The tests for the ballistics on it seem to have been done on Glocks and the reviews mention Glock 20's.. but is the second part, the lead ball, cause for concern when fired through a Glock with the factory barrel installed?
almost any ammo is now OK for a Glock Bbl...not that they have beefed them op somewhat, especially 40 cal Glocks,double tap makes some of the best ammo,but may be a little difficult in the recoil dept, especially in 40 cam and 10 mm....IMHO
My Lyman black powder book indicates a .395 lead ball weighs 92 grains. Since Double Tap uses a 95 grain ball it may be .400 and contact the rifling...
