Just got a TC encore prohunter stainless fluted 15" barrel in 243 cal.
Plan on reloading 100gn Sierra spitzer boattails using winchester brass and federal 210 large rifle primers. Purchased IMR3031 powder on the advice of a gentlman on another forum, but have been unable to find any listings for "how much powder" to use... One gentleman said 32gn to 35.5, but until I can find it in writing, I'm reluctant to load....
Any reloaded references would be greatly appreciated.
Happy New Year
