Need Load data for .460 Encore 20"; Barnes 275 gr XPB

[goathollow]

I'm wanting to load up some 275 gr Barnes XPBs to shoot out of my TC Encore .460 S&W rifle. The Lyman manual suggests something between 46.3-48.2 grains of H-110 (one option for powder) for that bullet. That isn't a lot of variance so I was just wondering if anyone has any experience with this bullet/rifle combination in a handload. I've loaded up some with 47 gr as a middle of the road but wouldn't mind going lower if accuracy is good. I will be using this load for hunting black bear.

I've tried the Hornady SXT 200 gr factory loads but they disintegrate on impact. I've killed whitetails and hogs with them but never gotten a pass through and frankly they make a mess.
