Congratulations on the buck!
Used the 115 gr Nosler Ballistic Tip from my .25-06 this year, muzzle velocity considerably less than your rifle at only 3,120 fps. Mule deer buck at 260 yards and a pronghorn at 160 yards - both one shot instant kills/drops. No recovered bullet, because both were pass-through hits.
I like those bullets. Accurate and lethal. Am not looking for a lot of weight retention with them, I like the quick expansion & fragmentation from lighter, faster bullets on deer sized games.
Regards, Guy
