Sorry James - should have read both post a little better. You could use the same load in the 10 and be safe, but it might be a bit low in the 10ga. If it were me and I wanted one tested for the 10, I'd load a couple with 30 and 32grs of Longshot and send them to Tom or Precision Reloading for testing.

The only figure 8 wads I'm seeing are 1 1/8oz are these the correct wad? Thanks

Craig, I've been using a very similar load to that, with bismuth, in my HE for a couple years now. Longshot powder, Nitro 27 hull, RP12 wad Cheddite 209, 1 1/4 oz. bismuth.

Very effective load on ducks.

Thanks for posting. SRH

I didn't read where the OP said it was a 10ga load, but a 12ga load. But with the 10ga in mind, many of us have found that any mild 12ga load can most certainly be used as a 10ga load. The chamber diameter is larger with the 10, so pressure has more of an area to spread out in, so pressure will be lower. Yes I know you're using a different wad, but IMHO even that isn't going to up the pressure were it's dangerous. If you have the powder companies reloading booklets and look up different gauges with the same powder you'll see pressure always goes down as gauge goes up. There's nothing wrong with sticking to recommended data, especially if you're reloading at the higher pressures, but at mild pressures it's still just reloading for shotguns - low pressure compared to pistol or rifle. Just use a little common sense.
