I run 4.1 grains of 310 behind a 230 fmj, and they come out at about 750 fps.

Yesterday, at the chrono station, for the Wisconsin sectional, a fellow shooter was running 3.7 behind a 230 moly, and he was good to go.

Every barrel, and bullet chromos a little different, so you need to chrono your load in your gun.

My USPSA round is 3.9 N310 pushing a 230 Bayou Bullet @ 1.25

"blueeyedme", Could you please share with us the chrono numbers for this load. Thanks :)

Nevermind . . . . Found a past post of yours :)

Like others mentioned all the stuff is subjective and you need to run them through your gun! I chrono'd some 230 rainier's which is a thick plated bullet yesterday. 85 degrees, 1.255 oal, win brass, 754 5 shot avg. out of a 5" 1911
