How much velocity do you get out of your 300 winchester magnum, bullets like 165 and 180 grains

Had various 300 Win Mags. Never broke 3100 fps with 180s and a 24" barrel. Used 4350 (all) 4831 (all) 7828, RL19, RL22, H1000, AA3100, and maybe some others.

My lot of MR3100 is an early production name for the current powder that Accurate calls AA3100. I bought that lot twenty years ago.

Mine : 3.050 fps 180 gr. 24 inch barrel.

I load RL-22 and a Fed 210 primer for my .300 Win mag and get an average 3100 fps. with 180 gr. Nosler Partitions. Good shooting.

------------------

Using 73 grains of IMR4831 and Nosler 180's, I clocked 3180 average out of my Sako 75 SS in 10c temps. There were no serious pressure signs so I could have exceeded 3200 fps if I had wanted to. Based on the accuracy I was getting, I settled on 71 grains that averaged 3100 fps.
