Not a big fan of Partitions anymore. I've hand loaded them in in various weights up to 250 gr. with varying results. On my only guided hunt ever many years ago, the guide called them "trackers", because they had to track a lot of elk shot with them. I think your limiting factor will be a shoulder shot. I'd rather have a heavier bullet for that reason, particularly if it's the only shot you have. I shoulder shot an elk at 75 yards with a 338 with a 210 gr partition and it did not break through the shoulder. The second shot did drop it like a rock through the spine. It really is up to the shot and shooter, but if you are off just a little, give me that 180 gr. in a 30-06 any day.
I do love their old "solid base" (discontinued) bullet for shooting deer. Best shots of my life were with that bullet.
