With all due respect, if you are getting a chronographed speed of 2800 fps with a 250 gr. 338, you are beating every factory round I've ever shot, and every reloading manual I've ever looked at. I got 2820 with a Nosler 225 gr Partition when they first came out, with 72 gr of H4350, but could never get even the published 2700 with either Nosler or Sierra 250's. This was with a 24" bbl. What's your secret?
