I know every firearm is a little different, but man my old Browning A-Bolt 7mm Rem mag loves factory Barnes VORtx 160gr TSXs. I have shot 1/2" groups at over a hundred yards off bags with it.
My FA83 454 has shot the XPBs pretty well too, maybe not as accurate as the 265 Swifts I have used, but still definitely minute of whitetail.
I even loaded some XPBs for my 45 colt that I am anxious to try at the range. we'll see how they work soon hopefully.
That stinks you have been having so many issues.
