I tried some "2400' , the books say 20-30 grains max, (potentially best load) but thats not enough to cycle the action on the remington7400 , and not acurate at all, for me anyway. I used a lee 155 grain bullet, out of Lee 155, 175 and 180 grain bullets which would you guys choose for a good bullet for 30-06 ?...accuracy and hunting load
