Thanks for a comparison, what element of the performance do you like best with the Hammers, what makes that differentiation for you? I'm curious which rendition of the Barnes you have used, TTSX, TSX, LRX, original X, etc?We've shot Barnes, Hornady and now Hammer copper bullets. I will say the hammer performance is the best of those three, but I still like the performance of the Barnes and Hornady. And with the copper, at least in my experience, your meat loss is significantly reduced. Thats why I switched.
I've used TSX and TTSX. The Hammers expand really well and still penetrate great. For example, my brother shot a cow years ago with a 130 gr TTSX out of a 270 at 385 yards. Heart shot, cow dropped, got up and ran 70 yards and died. Exit wound was maybe a quarter sized or slightly bigger. This year, brother shoots a spike at just over 370 yds, (still .270) quartered away with a 126gr Hammer Hunter. Bullet passes through, exits offside with a hole slightly less than a coffee cup. Bull goes 60 yards and dies. Same result, but better blood trail and exit with the Hammer. I also shot my muley at 470 yds with the same bullet (Hammer) and same results. Plus, you can push the Hammers at higher velocities, better BC than Barnes and shoot tighter groups. They are about 2x the cost however, but worth it in my opinionThanks for a comparison, what element of the performance do you like best with the Hammers, what makes that differentiation for you?

Muzzle velocity with Barnes was around 3000 fps, Hammer was 3200 fps.I get similar Barnes TTSX exit performance as you if it goes between ribs. If it hits or nicks a rib, it's a bigger hole but not coffee cup size. I am shooting a 35 Whelan AI with a 200 TTSX, however my sons use the 130 TTSX and 110 TTSX from an '06 and .270 Win respectively. All three are "light for caliber" and good results all around on elk.
What are the muzzle velocity's with your respective loads mentioned above?
You are correct. The Hammers are designed with a lower bearing surface, so they dont experience the pressure spikes which means you can use more powder. My loads is 57gr of 4451 IMR Enduron, CCI 250 primer and 126 gr Hammer Hunter. I can load hotter but the accuracy of this load was pretty ridiculous, ~0.3 MOA. I shoot a Win Model 70, 24" barrel.Is there any load data for the hammers, sounds like they have less pressure all else equal and must use heavier powder charges to get that velocity.
