Re: 300 rum
shoot 3 and let er cool off. work up load in 1 gr increments until you find accuracy and fine tune with smaller increments from there... play with OAL too. I usually just load to max magazine length and increase charge until accuracy comes in... usually close to max with the rums I have. I shoot accubonds in 7, 300, and 375. I like the idea of a fairly tough bullet that will fly well too. Anyway, thats my game. Others may do it different and better.
