I;m loading for my Sako and found a load that shoots exceptionally well but now I realize its on the low end of the charge weight. I'm using 56 grains of H4350 with a 150 grain Sierra Pro Hunter. I get three touching at 100yds but now realize its a pretty slow load, according to the book. This isn't my go to rifle for hunting and may never see the deer woods and where I hunt a 100yd shot is probably as far as I can shoot. Do I leave it alone or boost the charge and hope to find another sweet spot??
