[QUOTE="Alibiiv, post: 1683604, member: 69192"] I just purchased some 220gr hard-cast bullets from Rim Rock bullet company. Now that I have the bullets I cannot seem to find a load for a bullet heavier than 200gr for the 10mm.. I recently picked up a Hornady #10 reloading manual, the manual lists a maximum load of 7.3gr of Longshot for a 200gr bullet. I was told that Buffalo Bore uses "7.1gr" of Longshot in their 10mm ammunition. I guess I could do some pressure testing with different loads in .05gr increments, don't like doing that with a handgun, or any gun. With a rifle there are familiar signs when pressure is getting too high, with a handgun that is not such a luxury. I've checked some of the other forums, this situation does not seem to be unique to these bullets. What I did find was that for any accuracy out of the heavy bullets in a Glock the bullets have to be moving at least 950fps to stabilize. Any one have suggestions or resources for load data for the heavy, 220gr, hard-cast bullets? [/QUOTE]
