WOW Jeff, You agree with me. I have a G-2 frame but can't seem to get most of my barrels to work on it. I need to start playing with that. I think that by shaving a little off the locking lug that will fix the problem. I have extras from T/C so after Christmas, I'll experiment. I really think the 358x444. I will switch to Varget after ff done and see how that works. Merry Christmas Jeff.
