Hello. I will be firing some 202gr NOE 316299 boolits out of my M39 Mosin Nagant. I have both H4831 and H4895 powders, which were recommended to me for this application. However, my reloading manuals don't have any data for these powders. Based on my searching of this forum, I have come to the conclusion that 28gr would be a good starting load with the H4895, and 40gr for the H4831. Could someone confirm that these are safe/good starting points for my loads? Also, would the use of Dacron be advised in conjunction with either of these powders? Thanks.
