I just finished up a couple other builds and have been thinking about the next one. I have 100% decided on the .338 RUM. I would like to hear what is a common barrrel contour for this caliber. I will be building this for big game/LR varmints/target shooting. Weight is not a huge deal, but would like to keep it under 13-14 lbs. I have been looking and maybe something like a heavy varmint, or keep the muzzle diameter in the .9" range or so. IDK. What have you guys been using on your .338's?
