    I have read the Article on Longe range rifles on a budget. the author states he uses the Miculek brake from Brownells and opens it up to fit caliber. my question is what should be the I.D. for 300 RUM.

    20-30 thousandths over caliber

    .308 + .020 = .328" is ideal and not more than .338"
