Finally got around to loading up some 50BMG rounds last night after saving the brass for a couple years. I used Hodgdon 50BMG powder and Hornady A-Max bullets. The Hornady book gives the recipe as 214 gr of powder with a C.O.L of 5.730 inches, but on the previous page says the max C.0.L is 5.450 inches. Figure the 5.450 inch setting is for magazine fed rounds. The Hodgdon powder jug says 233 gr of powder with a C.O.L. of 5.450 inches. I used 210 gr and set the C.O.L. at 5.650 inches as this cleared the press opening without having to play Chinese Puzzle to get the finished shell out of the shell holder. I checked the shell in the chamber and it drops into the AR-50 no problem, with plenty of room off the rifling. (another .20 inches if I measured a dummy test load correctly with a bullet set way out ) Anybody else use the A-Max in 50BMG out of an AR-50? Would like some any pointers. Ive been reloading for a while, but the .50 is a whole new game to me and I dont want to waste a lot of time and/or money getting the hang of it, or worse yet, do something that isnt safe. But in general, if you compare two seperate sources of published load data, and see a substantial conflict of load information, which way do you normally go? 1. Go with the higher load? 2. Go with the lower load? 3. Split the differance down the middle?
