Appreciate the earplug Idea! (also dense foam)

I'll stick with RCBS Collet Inertia as I have used it nearly 35 years now, only having to replace the O-Ring 1 time.

I don't use it except when working up a load and seating too deep in my quite lose necks. I use LEE Factory Crimp and believe in them fully. I'm not a benchrester, other views may vary! I work on animals, only sometimes targets when necessary.
