[QUOTE="Fiftydriver, post: 58570, member: 10"] I have not loaded for the state arms but I use these componants for my LAR and will tell you that while Hodgdon lists a max load of 233.0 gr for the 750 gr A-Max. My rifle will blow a primer pocket at around 227.0 gr. My LAR has the match chamber but it is not overly tight. Start in the 205.0 gr range and work up from there by 2 grains at a time and after every shot rechamber the fired case to check on pressure levels. At around 50,000 psi, cartridge brass begins to permanently form under pressure. At this point you will begin to notice the force needed to close the bolt on a fired case will begin to increase. The 50 BMG should really be run in the 50,000 to 55,000 psi range in shoulder fired rifles so once you feel the force needed to close the bolt on a fired case getting noticable, your getting in the area you want to be. My top load is 223.0 gr in my LAR which produces right at 2720 fps in its 36" barrel. My match loads are loaded with 212.0 gr. Good SHooting!! Kirby Allen(50) [/QUOTE]
