I pushed a few out of an SP 101 (bought it 'cause I liked the red tips).
Fired OK, but was pretty dirty. I suspect the cartridges are formulated for longer carbine barrels, and don't function quite as well in a shorter pistol barrel.
I've relegated it to the drawer until I get a carbine.
This was my question about it.If the bullet is designed to perform at max from a rife/carbine length bbl,I was curious about the actual performance from handgun.I've shot it in .357's and .45 Colt... and while its perfectly good ammo, the bullet itself didnt perform well in my tests. Very little expansion in either caliber (there are videos on YouTube showing the same thing). It may be fine out of a carbine, but I wouldnt buy any more of it to shoot out of a handgun.
