[QUOTE="adamsredlines, post: 3640089, member: 40561"] Anybody know of a calculator you can input all your info into (cartridge, bullet selection, seat depth, powder choice, etc) and get a ballpark but fairly accurate FPS output? The reason I ask...Jack Lott's notes show his original load was a 500gr pill over 75-85 max gr of IMR 4320...but if you look up loads for that combo they're all way under that. Hogdon doesnt even list .458 Lott on their site so there's not even a base load from them. I read Hornady says a max of 77gr of 4320 for 500gr Lott...but they also got "low velocity" using that load. I'm curious what the loads would do as intended by Jack Lott. My understanding is when he went to get the cartridge SAAMI approved they reduced the max pressure and thus got "reduced" loads. I know, its goofy...but I'm still curious and not sure I want to risk my shoulder to find out :) [/QUOTE]
