Looking into ordering a 22br barrel for my Encore Pro-Hunter. Already have...and REALLY like a 6br barrel from Thompson for the same rifle. Just looking for the "do's and don'ts" for the brass (guess ya full length re-size the 6br stuff) before your off and running. Anyway,..I'd love to hear from some of the 22br folks & here how you approach it with some good starting point loads to get up & running. Thanks in advance!
