I have a Bushmaster Predator with a 9" twist and the Sierra 69gr Matchking HP worked swell on prairie dogs/rabbits. I never used it on game though. I would agree that the 62gr Mono would be a great one on hogs/deer. I am one of those that believe a faster spin helps in killing power, especially in smaller calibers. I used the Hornady 68 OTM in a 9" twist 22-250 AI with fine results, its also a tough enough bullet to hunt game with. The 75gr Swift in a .224 TTH was awesome too, but it had an 8" twist. I never tried it in the Bushmaster.
