XTP is one of the best bullets I have ever used. If you are having issues with separation go to the 300 on hogs.

I have driven 44 cal 300's as hard as they will run in an Encore Rifle and pistol as well as a Contender. Look at the photos in my bragging board. There is a photo of a 300 gr XTP driven very close to max velocities with near 100% weight retention.
