IF the ammo is truely commercial remanufactured by a commercial loader with product liability insurance, OK.
Companies like Black Hills are great ! Their 223 reman outshoots most factory
as the brass is cleaned, sorted, trimmed and reloaded like new ammo.
BUT shooting reloads or remanufactured ammo Voids gun warranties like Glock.
.............and they can tell IF damage is done by reloads as they will want the brass from any round that caused a failure.
IF you reload ammo and stay within recommended load specs, you should be OK....but do assume liability for damage to your firearm.
New commercial ammo is usually loaded to SAAMI specs for safety. That is why is complies with firearms manyfacturers warranty statements.
I would NEVER buy some Bubbas reloads at a gun show as you have NO idea what the load is.
