Small entrance and small exits are the norm with Barnes X, XCL, TSX and TTSX.
I've been using Barnes since about 1992, and have not recovered one from a big game animal, yet. Last fall, my son shot a cow elk at about 240yds, using a 243 and the 80gr TTSX. She was facing us and went down so fast I thought he might have missed, except that I heard the 'womp' of the bullet hit.
She was facing us, and I think she dropped straight down. We did find one petal, but we did not have the time to dig around and find the rest of it due to darkness and the Old Man (me) not having fresh batteries in my headlamp. He was using the flashlight on his phone to light things up and show us the way back to the truck.
The shot was head-on, and the TTSX hit the left shoulder joint and busted it up pretty good.
I use the 45gr XLC, the blue coated ones, out of my 22 Hornet for coyotes, and it's the best bullet I've found for coyotes with the Hornet. When I run out of the XLC, I'll buy the TSX.
