Hi. The following is mostly just in the brain-storming stages, but help would be appreciated. My friend recently acquired a 12 gauge press which is currently set up for 3" shells. Neither of us has reloaded before, but we have the required manuals and several books on the subject of shotgunshell reloading. Our reloading would be solely for sporting clays as that is at least 90% of our shooting.For fun, I am wondering what kind of loads can be arranged in a 3" shell. This is not for any formal competition, so meeting some international standard doesn't need to factor in. I was hoping a reloading guru had some thoughts on a 3" shell loaded with 7.5 or 8 shot. Though my friend has a pump, I have a gas-operated semi, so the shell would need to be able to cycle a Beretta AL390. I figured a 3" shell could hold enough shot to darken the skies, and would be a hoot for friendly clay-shooting.
