Yet another way to make 300-221 fireball brass

Okay, that makes sense to use the pilot, but you don't have to switch pilots once the hole opens up past the size of the 22 pilot? I may have to check that out.

Colohunter, you will not be able to hold that case in your fingers tight enough to trim the brass. You need something MUCH more rigid.
