I'm just beginning a new build of a 7mm rm, and by now I suppose that everyone knows of my fondness for the .264 wm. I've never loaded for 7mag, and am wondering if there's that much difference between .264 & .284 coming from the same case??? I've looked at a lot of powders, including some very reasonably priced (military powder)and plan to make one HUGE buy from the same lot, so I don't have to continuously play with load development after finishing each 1# container (which happens too often.) My question is, what's your pet powder for these calibers & why. I'd much rather be working on other factors, instead of load development so often. Is military powder as good as name brand? What do you do to remedy this problem??? Since my wife and 2 sons started shooting with me every other weekend, we go through a lot of propellant! Thanks for your experience!
