I am thinking about playing around with XPB's in my 45 Colt Super Blackhawk hunter and my FA 454 Casull.

However, I like the looks of the velocity one can get with the Colt, but the 454 loads I have found seem a bit light. I know you can't drive them as fast as others because of the case volume and such. If I could load the 454 up like what Double Tap gets out of theirs, I think I'd be cookin, but don't know if this is possible with handloads.

but I was curious what loads do you guys use?
