I am doing some reloading for a 350 Griffin & Howe and was wondering about different powders. I am currently using IMR 4350 but was wondering if their was another powder that might be better. I have been using 70-74 grains of the IMR4350. The problem is their is no reloading data for the 350 Griffin & Howe. Cartridges of the World shows a couple of loads but I'm a little scared of using that data because they are using 88gr of 4350 and 93gr of 4831. I know it says max. but sure sounds like alot to me. Thanks for any help.
