Laddered to 57.5 last week with 140 accubonds and Superformance in a rush for the weekend, never loaded either before. 57 gr produced 2900+ with no visible pressure just a slight increase in bolt lift weight.
From what I have read and can see, I think 60 gr should be ok. Considering that 60 gr of IMR 4831 was the go -too with 130 grn pills and it is a faster powder.
Not wanting to highjack the thread, but what distance from the lands is working for the AB's ? I seated at 40 thou and when I compared these loads to factory stuff with the comparator they were plus another 300 thousandths more jump !!
