I will try them in my .460 Encore when I can find some. I have been shooting the Barnes XPB 200 grain copper bullet with H110 in my 460 Encore since I got it. Best accuracy, fast and hits hard. I have had no deer or hogs walk away with one of the 200grn XPB in them.
I tried heavier bullets but didn't find the accuracy. Might have tried more loads but when I have this load that does it all for me, I'm sticking with it. I wouldn't be worried to try it on Elk or game of that size. I'm not sure what velocity I'm running with the 200's but it works.
I did load some XTP's and they shot good but are a little slower according to the Hornady manual.
