Hmmm.... I'm currently looking at buying BM8208 largely because it seems to be the go to powder in my 35 Whelan. I know most people like to use a specific powder for a specific cartridge,but I've gotten away with using 2206H in everything I own for years now,so I'm intending to try to do the same with 8208.
Now,researching the ADI manual,it has data for my 22/250,308,35 Whelan, and 45/70....but not for my 358 winchester. I kinda find that odd,as I can find data using BM8208 in the 308 cartridge right up to 208gn pills,which would lead me to believe it really should be fine in my 358 with 180gn pills.
So....should I try BM8208 in the 358 using the 308 load data ? In theory it should produce less chamber pressure due to the increase in bore size. Has anyone tried ?
