Recently when I was helping clean out my late Mother in Law's house,I ran across a metal ammo can that belonged to my late BIL.Inside the can was 2 zip lock bags containing 100 rds each of 45 acp FMJ ammo.They were all Federal brass ,but I am figuring they are reloads.My BIL had various guns and was a member of a range in a neighboring town,but since he has been dead about 1 1/2 years I don't know how to find out about them.The brass is still shiny with no corrosion.The question of the day is ,should I try shooting them,not knowing the loads.The only 45 I have is a newer Colt Competition, and I don't want to screw it,or myself, up by shooting some HOT loads.What say you ammo experts?Try some or leave it alone.
