I meant .284 not 280. Should be easy to get 2900 out of a 26" tube with the 180's. Mute point thogh if he doesn't reload. a 300WM and Federal fgmm with the 190 smk's is probably your best option.
All loads used neck-turned, Winchester-headstamp .284 brass, CCI BR-2 primers, and naked (non-moly) Berger 180gr VLD bullets seated .010" in the lands:
51 gr RL 17 - Mean Velocity 2881 fps, ES 17, SD 7 - No pressure issues at all
52 gr RL 17 - Mean Velocity 2953 fps, ES 19, SD 7 - No pressure issues at all
53 gr RL 17 - Mean Velocity 3003 fps, ES 25, SD 10 (Slight sticky bolt lift on 3 rounds - this is about top end for my liking but I would not hesitate to shoot it however if it turns out to deliver good accuracy). Big Speed Gain with Reloder 17 in .284 Win
RL 17 clearly enables me to run the Berger 180s easily 125-150 fps faster that I normally was able to shoot them with H4350 and H4831SC in this rifle. My previous load ran around 2825 - 2850 fps with the Berger 180s and that was about all I could get out of it
