hey guys, i ordered up some lead 500 grain bullets for my s&w 500. ive got the lyman cast bullet handbook but it only goes as far as 440 gr. so far ive onlyloaded 410 gr bullets from this thing. so im wondering what the OAL should be for these guys and also a powder quantity for the 500 gr using lil gun powder? the book with a 400 gr calls for a 2.00 "oal and says to start t 27.7 gr of lilgun, and for the 440 gr bullet says the oal is to be at 2.010 inch and the starting point for lil gun to be 27.4 gr. so naturally id say to extend it to say 2.020 and start the powder around 27 gr and that should be safe,but then as i look at the 375 gr bullet length its calling for 2.035 " anyways, im wondering what you guys would suggest i do for powder weight and oal. this is what im using for bullets https://www.midwayusa.com/product/182264/cast-performance-bullets-500-s-and-w-magnum-500-diameter-500-grain-lead-long-flat-nose-gas-check-box-of-50
