My factory ammo (3132438) velocity, 2670 avg. was taken at 39 degrees f. 22" barrel.
Same day my hand loads, 41.5 h4350 / federal gm210m / 140 Amax / new brass averaged about 2685fps. Accuracy was no where near as good as the factory stuff. I did have pretty good accuracy with the same load using Hornady 140 bthp. Around .5 moa vs 1 moa or so with the Amax. Didn't think much of it though since I hadn't done any load development yet.
I only loaded the 140 amax. I loaded 41.5 42.0 42.5 and 43 grains of h4350. The 42.5 shot the best with 42.0 being very close. 41.5 and 43 didnt do so well.
