Though by no means near a max load in my Stiller/25" Krieger 1:8, I stumbled onto 41.0 H4350/Fed210 primer/123 AMax in reformed 300 Savage brass that came with rifle when I bought it with around 600 rounds through it and it was so consistently accurate, I've not had reason to press further, though I feel certain there is more velocity to be had. 2852/37/14 at 97d in August last year and 1/2" 5 shot groups at 100 a regular thing. Very easy on brass, and have 100 rounds of Lapua brass sitting on the shelf when 300 Sav brass gives up the hunt. Have had it to 1000yds on steel a few times, but no regular range work to tell you how it does on paper at 3-500 or so. Same charge with 142 Sierra moly SMK's around 2725 at 47d.
