I'm addicted to the 30-06 and have rebuilt a 1903 Springfield into a sporterized model. The barrel and action are solid and in good shape. My question is, I'm working up a load for it and am using Accubond 165gr bullets in front of IMR 4350. With 55gr of powder I'm keeping a 4" 5 shot group at 300yds. In the Nosler reloading manual it shows 57gr as the most accurate load and also the max load for this powder. This load should be more accurate, especially as I get out to 700-1000yds...but is it too much for my rifle. Thanks for any and all comments.
