Thank you sir! That works for me!

My Kimber 84L 270 shoots anything so very well. It loves the 110 TTSX and the 110 Hammer, plus the heavies on the other end! From my observations of the Barnes, I think the Sierra 120 Pro Hunter "should" be better on deer/antelope. I have shot a wad of Hammers in several calibers but never killed anything with them. I have used the PHs in other calibers and they acted just like Partitions. We shall see!

Hey Preacher, last year I shot a whitetail doe during our early antlerless season using my 270 with the Sierra 110. Wasn't running it hard, maybe 3100fps or so but placed the shot behind the shoulder thinking it might blow up, but it didn't. Complete pass thru with about the same damage as a 130gr Sierra. I was pleased with the bullet performance. Had I known it would behave as such I would have poked her thru the shoulders Dan.

First time I saw how tough the Pro Hunters were was back in late 90's. Federal factory loads, 300WM, 150PH. Shot 4 deer in Llano Tx. Made a 50 cent pc exit, with alot of lung tissue syphoned out, hanging. Wow! ha I too thought they would be a "bomb", and stay inside those little Hill country deer. Nope, acted like I've seen NPTs. Awesome!
