Don't have one (BOY! Sure wish I did though!) but if I did have one, I'd go the Buffalo Bore non +P load mentioned above. I run their very +P version of it in my carry J. My Wife's J has their 150 (non +P) full wad cutter in hers. Her Model 66 is loaded with B/B's, and my 696 as well. You can believe their velocities, they even state what actual guns they were fired out of for chronograph results. Pricey to be certain. But have you priced high quality self defense ammo at a gun shop lately?
