Have a T3x Lite I want to rebarrel to 22 BR for a lightweight coyote\ walking varmint rig. 53 vmax, 55 BK, and 60 TMK are the bullets I am interested in running. I found plenty of posts about the BR case working with an AICS mag. I can't find anything about the factory mag (not the CTR mag). Anyone have success with this setup?
