Dean, great thread. I am impressed that you're going one out beyond 22BR! I shied away from running a 22BR (fast twist) I got used/unfired a few years ago. Had it re-barreled to something more standard.The 22 X 55 I use 22BR or 223 WSSM dies 6.5 X 55 brass it has to be necked down to 6mm first then 22cal.
