Gentlemen, while I don't participate in actual Benchrest shooting, I still use very much the same equipment and hand tailored loads for my rifle, and seek premium accuracy from my rigs. Not sure if I should call them Varmint or Target Rifles, but I always seek 1/4" 5 shot groups if possible. I'm getting ready to order a 7mmMag barrel and a match grade reamer. I'd like to keep this rifle at 11-12 pounds with the scope if possible. Therefore, I want the minimum weight barrel that will be sufficient for a single tight 5 shot group at 100 yards starting from a cold barrel. That is my goal.
Choices;
A)The Krieger Remington Sendero sporter contour barrel is 26" and .830" @ the muzzle and aprox 4.5 lbs.
B) The Krieger tapered #8 "Varmint & Match contour" barrel is 26" and .820 @ the muzzle, and aprox 6lbs.
Question:
If I only shot a single 5 shot group out of the Rem 7mmMag cold barrel, will either one of these barrel contours allow a single sub-1/2" 5 shot group before the barrel overheats? (ie; will accuracy degrade after the first 3 or 4 shots?)
