I'm looking to get a mold for my 44 mag handi rifle(I cast all the time but just not for 44 yet) It has the 1 in 38'' twist barrel. I've shot 245 grain cast bullets out of it and it seems to do pretty good. But I love heavy lead and was wondering if a 310 grain bullet would be too heavy to stabilize out of such a slow twist rate barrel. I shoot the 245 SWC's with 8.2 grains of unique, no clue on the velocity, but according to lymans 46th it should be around 900 fps. I'd like to keep the 310's around the same, maybe see if i can get to 1000 fps with out having to buy all the stuff to install gas checks(I don't size my lead, and my 44 plugs at about .435 any way) Any advice would be great, Hope I posted in the right section mods feel free to move if needed here is the mold I was looking at getting : http://www.midwayusa.com/product/51...cf-430-diameter-310-grain-flat-nose-gas-check Wanna kill these ads?
