Barnes uses pure copper which is softer than the alloy gilding copper that most jackets are made of that's why they leave some copper in the barrel. They cut grooves in the TSX, TTSX and MRX to stop this so it's not such a problem anymore. Hornady and Nosler use gilding copper in thiers so they don't foul any more than regular jacketed bullets. So now we have copper bullets with grooves, gilded copper bullets with grooves, and gilded copper bullets without grooves. I don't what the Trophy Bonded Tip it made of. It'll be interesting to see how they compare pressure wise, less pressure means higher velocity. Also those grooves lower the bullets BC.
I love all these new all or mostly copper bullets. The more choices the better and maybe the competition will bring Barnes prices down. Too bad North Fork folded up they were great.
Enough is enough. Build and guard the border fence around California.
