I have six different batches of sample cast projectiles ranging in weight from 228 to 310 grains and would like to put together some low to mid-level loads for these. Some of them are gas checked and the rest are plain based, including the 228 grain and 310 grain bullets. Mostly I have been shooting heavy 320 grain gas checked castings for deer hunting with heavy loads of H110 and W296, and don't seem to have listings for lesser loads with these other, lighter bullets. So, does anybody have any suggestions for powders and amounts?
