T7, I wouldn't panic. Use what you are dialed in for now... and re-adjust later. Shoot em in the heart/lungs, you'll be fine. If you DO get the chance to shoot before hunting, I'd load up them gold dots and it should shoot right with the XTP's.

IMO, Gold Dots /Deep Curls are a superior bullet. I prefer the 240/.429

460 no excuses.... LOL, those will work too
