My absolute favorite bullet of all times. I can’t speak for the Weatherby as I don’t care for Weatherby mags ( not saying there is anything wrong with them just a preference thing) but..... out of my 308s, 30-06, and 300WM the 165 TTSX is amazing. I’ve killed everything from whitetail, mule deer, and hogs to the ________(fill in the blank here) exotics. Between myself, my kids, guides, and clients this is probably the most common and without a doubt most effective bullet I have experience with and the TTSX is the only hunting bullet I load anymore.
