[QUOTE="Jud96, post: 1880535, member: 69478"] I did a lot of testing with the .300 Win Mag barrel I had. I used IMR 4831 and IMR 7828, because RL26 wasn’t out then. I tried everything from 175-208gr. I was able to get 175s up to 3200ish without pressure with IMR 4831, and got 190s around 3100fps. That’s impressive to see you getting that speed with 180s and RL26. I know I used completely different powder and bullets than what you’re shooting, but it still shows the .300 WM can be very potent. It seems like the .300 Win Mag always seems to be underloaded with 180-190s. [/QUOTE]
