I am guessing you mean barreled or can you bore out a 30-30 to something that large and still have meat on the barrel ? I also did not know the action and everything else would be able to take that much more from the big bores. Have you looked into it and the costs ? Just curious .Taylor said:I have a Marlin 30-30. If I get it rebored to 375 or 444, what twist rate would be the best for cast bullets?
The first article I ever read by Paco was "444 Misunderstood" judging by this article he does not understand it very well so at least the title is accurate. I have heard he has quite a following. It really makes me wonder.Canuck Bob said:My MG handles 265 FN Hornady bullets like a target rifle. There are lots of reviews that report strong performance up to the mid 300 range from very credible sources.
In your weight range, same as mine, you can expect superb performance. Early 444s have a reputation for accuracy and I now believe that has a lot to do with MG and the easy twist torque from the 1-38" barrel.
I am just gearing up to cast but the formula is always the same. Slug your barrel and throat to KNOW your sizes. Fill the throat not the barrel, most report .432 as a good start. Good articles below.
Bob - FWIW the Beartooth® 290gr LFNGC Cast Boolits that I have weigh 296gr. I further know that Beartooth® lists the following weights for their 44 cal boolits: 240, 250, 260, 265, 280, 290, 300, 325, 330, 355, and 405gr.Canuck Bob said:The 444 is a superb game rifle. It handles large blacks with real authority. It shines with black bear and moose. Your bullet choices will be fine. If you want to try some heavy bullets a bunch of guys here like the Beartooth 295 grainer. Personally I just ordered a cast mold for 270 grains solid or 250 grains HP.
