Most old factory made ammunition will fire well. Was given a grocery bag(paper variety) half full of .45 ACP one day when stationed in Calif. by the local PD. The was ammo from the 19 teens, 20's, 30's, 40's and 50's. Probably 500 rounds, all of it went bang except six rounds from 1936. I shoot 20-30 year old rimfire ammo all the time.........works as advertised.
