If you want to take pictures, and be part of the club, use a frangible bullet and document it. If you wanna kill an animal just as dead, not worry about lost meat, take hard angle shots with confidence, but not be part of the club, using copper works great. I've probably been using them as long as anyone around here (Barnes bullets from 1994 all the way through 2024). Hammer bullets are a great design differentiator from Barnes and other mainstream copper bullets. That said, I have zero reason to change from Barnes in any of my rifles.
I have some Hammers for my 35 Whelen AI. Honestly, no reason from a performance perspective of 30 yrs and many critters (and many calibers) from pronghorn to whitetails to muleys and elk to make a change from the current TTSX lineup.
