I enjoy 10.9 gr of Unique pushing a 240 jsp. I see now that Alliant is recommending 10.3 gr max, but the 10.9 is very pleasant in both of my hunting handguns -- Super Redhawk, and Taurus M44 (both scoped, adding to the weight factor). They are not painful to shoot in my large hunting guns, and I have no trouble shooting off a few dozen at the range. Several deer have fallen to that load from 5 to 85 yards, but it's still pleasant enough to target shoot for fun.
I'm getting a new trail gun soon, and will be working up some even lighter loads with Unique. I will post them here. Good luck.
