You don't want to push lead bullets out of a rifle too fast, try to stay with a slower powder and at the lower end of the velocity scale. Slug your barrel and you might find it is slightly oversize .323 if it was a military issue. All my reloading stuff has 15 years worth of moving and dust. Somewhere i have a few A2'S, rockchuckers and lubrasizers stashed away. I remember having a 98 mauser 8x57(sold) and a Lyman mold but i am thinking it was a lighter weight, maybe 120-130,140gr? You want anything harder than pure lead, wheel weights are good. You can weigh them after they come from the mold with the sprues cut off, heavier ones are softer. Geeze, my digital scale was one of the last things i remember buying, it was made in USA, been awhile. Going deer hunting for first time in 12 years, 308 handloads, 165 grain Nosler, no idea what powder, benchrest primers, load was mild but shot good, i have 8 rounds left, either i start reloading again or go buy factory rounds(most of my rifles have never seen). I haven't searched yet, but i bet there are a few good reloading website or forums out there.
