[QUOTE="Calvin45, post: 2798207, member: 109862"] I must say as well this .257 Weatherby cartridge itself goes against everything I’ve heard regurgitated as “common knowledge”. Maybe common knowledge is just cognitive bias that’s normalized. Because it’s wildly overbore, has a ton of freebore, has a weird curvy shoulder, and headspace’s on a belt (I always full resize)….all of those things should be detrimental to accuracy and consistency and make it very finicky and picky. But it can be made to produce tighter es numbers than my .243 or 270 ever do with barely any work. The first load I just slapped together was with 100 b tips at standard length and a warm charge of 7828 - 3700 fps and under an inch shooting from prone with no real front rest at all. I’ll take it. The second load was a middle of the road load with 100 tsx bullets at just under 3500. Extreme spread of 10 feet per second, no tinkering or fiddling. I don’t get it. But I’ll take it! [/QUOTE]
