I have been using Barnes bullets in my 7 mag for a very long time.
I shoot 140's and 160's without having to adjust my scope.
I have shot deer, antelope, and pigs and have NEVER had an issue with a bullet failure.
I use the TTSX in my .243 and the gun loves them. again, never had a failure.
in my .223 I use the Remington Razor back in .64 Grain. Ive killed a lot of pigs with them and have been impressed with their performance.
Ive yet to have an animal complain that I shot them with a copper bullet...
