Thanks for the welcome! I used the Nosler ammo with 168 grain etips. I've also had great luck with the Federal Trophy Copper, which are supposedly etips with grooves. My rifle shot them and 180 grain partitions well. I was leaning to the partitions but the outfitter really likes Monos. I'm sure either would have been fine. I was suprised that I didn't get many exits. I just attributed it to the larger animals and shot angles. Nothing went far or needed more than one shot.
