If you haven't tried it, the 250 grain lead SWC and 7.5 grains Unique has been recommended for years. It's quite accurate. However, and keeping in mind that felt recoil is different for all of us, try a few rounds of this load if you're curious about it.

If the recoil doesn't bother you, then load up a bunch. I think it's a bit stout if I'm doing a lot of shooting.
