I'm torn between posting this here or in the Rifles, Bullets, Barrels and Ballistics forum, so hopefully I've picked the right place. Can someone help me with barrel contours, specifically what would be a good starting point for a LRH rifle buildup. Ideally I'm after a light-ish rifle but not a featherweight. I want to be able to walk around without thinking I have a HB varmint rig on my shoulder. The country I hunt varies from open grassy paddocks to forests with logged mountain sides. In both areas I'd be looking at shots in the 500 to 800 yard range, possibly up to 1000 yards at the extreme. The starting point is a Weatherby Vanguard SUB-MOA in .300 Win. Mag. After a bit of research it seems they have a #2 contour barrel from the factory. I measured the barrel as 0.615" at the muzzle. My first step will be to bed the action and free- float the existing barrel, but this can is bit of a crap shoot with a sporter weight barrel. The measurements I've seen for barrel contours don't seem to be consistent. The last one I saw had a #4 as being 0.650" at the muzzle and a #5 as 0.700", but that puts my standard barrel as close to a #3. So, I guess the question is what contour would be a good compromise between weight and accuracy when free-floated, and should I put up with the extra weight and go for a 26" barrel or stick with a 24"? I'm currently thinking 3/4 MOA for deer-sized game at the ranges I'm talking about. Thanks in advance.
