I have a new ruger Mini 14,I bought a case of the Tula very cheap.I had 2 misfires. I checked the ammo no powder. I called Ruger they said if you use that ammo it will void the warranty. I returned the ammo and bought some Federal.
BTW that Tula only has a very light copper wash covering a steel bullet. I am not in favor of sending a steel bullet down a steel barrel, just saying.
