semi auto? i am understanding you can use the brass twice...once brand new, and one reload..

i shot reloads on accident,
bought them at the range and they reload and put them in the empty boxes that people leave behind....
any ways...one exploded inside my glock, it felt like a fire cracker went off in my hand, the brass was cracked and jammed the next round up...after i cleared that i had to pull the brass out with needle nose pliers..

i'll never shoot a reload in any of my pistols again.
