Nice shooting! Seems like the rifle likes that load.

The .40 cal 200 grain XTP is all I've used for deer since I started muzzleloading 4 years ago- 3 shots, 3 kills. I have the utmost confidence in this bullet at muzzle velocities up to 2000 fps. Hornady claims that it is good up to 2,300 fps or so - I can't attest to that, but I can attest up to 2000 fps. The 200 grainer expands reliably at a wide range of velocities and penetrates good - I've always gotten a pass-through (though this year the bullet was found lodged under the far-side hide after busting the far-side ribs). Go with it!
