Re: 300 rum-200gr accubond-retumbo powder
3200, should be possible, I get 3160-70 with 94gr of retumbo with 210gr bullets. Start around 90gr and work your way up, the accubond has a little more bearing surface than the vld type bullets so pressure may come a little sooner. I use rem 9 1/2m primers.
