I've been loading my 6.5x55 Swedes and Norway Krag with #266469 ACWW . My charge has been 19.6grs. H4895 as per the Hogdon formula , i.e. use 60% of the maximum load ...I guess I've errored and been using 60% of the start load....also , at some point in time , I began using US milsurp pulldown IMR 4895...I've got these clocked at 1525fps/mv....any potential problems using the milsurp IMR 4895 vs the H4895 , I can't see any reason as the burn rates are so close ? What say you ?Thanks in advance...Tedly
