[QUOTE="Lefty7mmstw, post: 863174, member: 48043"] 165 to 200 grain- rl22 180 to 220 grain- 7828 or h1000 newer h4831 blows chuncks compared to war surp stuff imo; I've shot both and there isn't really any reason the new stuff should be so slow as the pressure comes up the same; the last time I tried both in the same rifle ( a 300win remmy with 180's) new manufacture h4831 was over 100 fps slower with equal or higher pressures. As to primers, you can get by just fine with most stick powders on standard primers in a 300win unless you are shooting in cold (sub freezing) weather. I use 215's in my 300win, 7stw, and 300 rum; my other larger cal's get a mag primer but not always a 215; I'll shoot in some darn cold temps. though. [/QUOTE]
