Can't see worrying about performance, but I will be interested in others results over the next few years.
Regular Sierra's work just fine and have a long history of good performance on game. My 308 is stoked with 165's Sierra BT's for this falls elk hunt. Had I had time to work with the Gamechanger I would have used those with confidence.
Sierra does tend to think test things pretty thoroughly before going to market. One reason they are so slow with new products. I can like that.
And all this time, lo these many years, I thought you were a Gen-U-Ine, dyed in the wool, Partition guy.......................
