Do not shoot in a rifle, bullet stuck in my Mossberg 144 LSB. I thought it would be great to practice at home with the same rifle I shoot in club matches.................Bad idea. I saw no warning on the box, I wish I had read reviews. No one got hurt and I don't think my rifle is damaged but the whole thing is upsetting. DO NOT FIRE IN A RIFLE.
It fired fine out of my Remington 597 rifle as well as my Sig/hammerli trailside. Of course, it couldn't cycle, but it fired fine.
My and my buddies had a bunch of fun with this and bolt-action marlins and S&W revolvers since you don't need earplugs and wearing muffs/plugs for long periods get annoying..
Be aware, this ammo cannot be fired out of a .22 rifle, as the bullet may not have enough energy to get out of the barrel. So says the box anyway. I don't think I want to test it out on my rifle.
