I've been reading some reloading guides and data, and with the market the way it is, the "recipe" that's published just isn't available. For example, I have a bunch of Winchester brass, and Remington 115gr FMJ projectiles. Looking at the Alliant reloader's guide, all their listed 9mm stuff is with Speer components and CCI primers. In their load data, it looks like the charge and the OAL change with projectile weight when using the same powder and primer.
So let's say I choose their Bullseye powder to use with my components. They list their load data for the Speer components as OAL@1.125 and max charge@4.7gr. Is this stuff pretty standard? I know the shape of some bullets is different, so where is the safety margin? Do I match the OAL and start at something 10% less charge? One of the disclaimers they have is "Use only the brands of powder and components shown in our tables. Do not substitute other types." I can't believe it's that sensitive because of what I've read on other guides. On Hodgon's site, they list 2 different bullets for 155gr loads. There's a difference in OAL and diameter of the projectile. I really haven't been able to find any load information for the Remington projectiles, but I can take physical measurements. The diameter is the same as the Speer listed in the guide at .355. I'm going to keep reading and searching, because there's got to be way to determine a margin of safety, but I haven't seen any.
