I'm new to reloading, my first project will be developing a load for a Cooper model 52 with 1 in 10 twist, 24" barrel. After looking at dozens of threads here, sounds like I may have trouble getting heavier bullets to stabilize with this barrel. I'm looking for a recommendation on what grain weight Hammer Hunter bullet would be ideal, and a starting point on powder. I just bought a pound of H4350, but can go to something different if advisable.
This rifle currently shoots factory Fiochi 180 grain swift sciroccos sub moa, but I'm looking to switch to a monolithic bullet. Would it be wise to start with the 181 grain hammer hunter, or should I go lighter due to the copper bullet and 1 in 10 twist? Intended use is for elk and deer, max distance for me is 600 yards.
