Hi, It's just me being a pain, again. I just read thru the entire 10 page post on the Tommy. A bunch of good stuff, BUT...... Based on your (and your friends) experience, could you give a quick rundown on what you feel is the approximate correct barrel lengths for a couple of different .30 cal. cases? Specifically, I was wondering about a standard 300 RUM, a standard 300 Win mag, and a 30-338 Win mag. I think it's time for me to step up to a new barrel, and I don't know which way I'm going yet. Your answer MAY make a difference. Thanks for your time. C'ya. John.
