[QUOTE="Orion2010, post: 931622, member: 51656"] 30" with a 10" twist will run to potential. Wouldn't go much shorter in order to burn all that powder. I agree you did your research I replaced my bbl and have this in a Shilen air bbl Over factory it's night and day. Powder is the key , low and slow but drop tube to pack it in. Love H870 if you can find it or stock piled before. Use 129 gr but work up to that The only close I found is Vit. V n570 works for accuracy and speed working up loads . 30-378 has been around a long time and still the best in the game. Long range flat is simple amount of powder ? Who has the largest case , don't read factory or reloading manuals you are pioneering work up a load . Bbl length cheats formula as slow powders burn down the bore. But matching bbl length to powder and bullet is range time . Still 30 bbl and case capacity , so 30-378 wins I've gotten 180 gr at 4000 fps FYI Steve[/QUOTE] [/QUOTE]
