Re: 300 win mag data request
No quick load here. Lots of experience with .300 Win mag and 180gr. bullets though.
IMR4350 works in most rifles.
RL22 gives great velocity, though accuracy was not there for me. (ie sub moa.)
Accuracy for a 180gr. bullet, choose your maker, was found using IMR4831.
I know that's not what you were looking for, but I hope it helps...sakofan....RL22 is the new go to powder for a .300 WM it seems.
It's only rock and roll....But I like it!
