The new Hornady reload manual has 50 beowulf reload data. Similar to mine to which I use H110 for powder. I've load 275 XPB and 375 XPB Barnes, 300 HP and 350 HP hornady. and 400 FP speers. Barnes work the best. The 275 XPB has a hollow point deep enough to use as a shot glass. Impact is like the fist of God.
Going to try some 300gr hornady FTX lever bullets next. Cheaper then the Barnes. Pointed bullets tend to feed better too. The 400 flat point speers don't feed well. 375XPBs feed the best so far. As far optics, I'm using a Bushnell Banner Shotgun Scope 1.75-4x 32mm. This provides you with a longer eye relief so you don't get scoped. Great scope for the range of the weapon.
My 2 cents
