These are the results. Be gentle, its my first attempt at reloading! All cases are once fired Federal, full length resized then loaded with H4831sc and Hornady 100gn btsp bullets with std Remington primers.
These were shot prone on a bipod at 100yds through my Tikka M595. The second group are obviously the best with 40.5gn of powder but what can I now do to tighten the group further I'm thinking of trying 0.1gn either way and seeing what that does. The bullets were seated 15thou off the lands, should I try different spacing
All advice greatly recieved.
