In my experience with the medium bores if you can get up to pressure with a compressed charge of imr 4350 they rock and roll. I have a ruger 22 inch 350 rem mag. 61 of w748 is 2670. Too small to run 4350 with a 35 bore. Regardless if you can compress the slowest burning powder that will work you usually get good results. If you can get it to pressure of course. I have a 300 weatherby with a 27 inch lilja. I use 90 of norma 217 with a 200 N partition. I have to use an electric razor to settle the powder. 3150
