I just chronographed my reloads for my 300 weatherby mag. I'm shooting a 210 grain berger with 76 grains of RL-25, with cci magnum primers out of a 24in barrel. It only showed up as 2562 fps! Does that not seem right to anyone else? I had the chrono at 15 feet. The factor Hsm with a 210 Berger says 3036 fps! I know factory is inflated a bit but 500 fps! It seems like I shoul be up closer to there maybe in the 2900 range?
