Re: Reloads not allowing bolt to close???
The advice about not shooting someone else's reloads is spot on. I won't even use range brass to reload because I don't know it's history.
The only reloaded ammo that is reasonably safe to use is that made by MAJOR ammunition manufacturers like Black Hills. Just because someone hangs out a business sign doesn't mean they have the equipment, or liability insurance to properly run an ammunition manufacturing business.
I'll bet that the rounds in question will be too long if you measure the case length at a datum line on the case shoulder, and you will likely find that they were not trimmed to length prior to seating the bullet.
It just isn't worth your hand, eyesight, face, or even just the cost of replacing a firearm to use unknown reloads.
I wouldn't even recommend disassembling the ammo for components, because you just don't know how many times the brass was fired prior to reloading. There is the chance that the person who sold the brass to the ammo maker lied, and said that the brass was once fired out of a bolt gun, when in fact it has been fired six times, the last time out of an old full auto weapon.
