I use these on plain base 45 caliber bullets. They are stronger then the aluminum plain base gas checks with zero damage installing.

Couldn't find any of my normal brand, so tried the copper Gator Checks... They install great; very nice fit on my .475 bullets... and shoot great too.. Will definitely order again.
