When my grandpa died, he had already sold his gun collection off about ten years prior ( ) but I found this old military rocket motor box (basically a giant version of the 50cal ammo cans) and it was full of old boxes of ammo, which were all fired so it was just the brass. There was a box of 30 carbine that was really old in there also. Most common in the box was 222 remington. Is there anything good that I can convert these to? Or am I better off trying to trade them for something I need? The biggest score in said box was actually a few hundred starline 38spl and 357mag brass, and 2 boxes of 44mag brass.. But those are being used already. I really wish he wouldve kept his guns though... Im curious as to what his 357 and 44mag guns were. I guess Ill never know.
