Thanks Mike. I use a pin-fire 12 bore and have some purpose made turned brass cases that I load and also use a similar method to you using swaged down plastic once fired cases. Problem I have is that sometimes the pins get stuck tight in the brass case after firing and can be real pigs to get out. Any tips on that one? I might try the Magtech cases. Do you have to turn down the rims first to fit the chamber on the gun? Thanks. Lagopus.....
