Thanks again for the info - in my experience the 139 Interlok FB have smashed through every time on Thar and Deer. The only bullets that haven’t exited were the 150gr Winchester Factory’s I purchased a few years ago for their cases and used up close in the roar. I actually see the Superperformance powder is cheaper than 2209 and RE 16/17 and may be good for a 22inch barrel...
