I'm in the same range as everyone else, treat a 10mm like a bow and keep it inside of 50 yards for best results. The 10mm is a good performer in a semi auto pistol, but it's still a pretty mild chambering in the big picture. It's not in the same league as a 41 Mag, and even that's on the low end of what I would consider for a dedicated hunting gun.
The 10mm is great for a "target of opportunity" sidearm. I've had Glock 20 and 29, Commander sized and full sized 1911s and an EAA Witness in 10mm as well as Ruger Blackhawk, S&W 610 and GP100 (still have this one) revolvers in 10mm. I've killed quite a few critters up to the size of blacktail deer with the 10mm and it works, but it's hardly a power house. It's better in the revolvers where you can load the rounds longer and get a meaningful increase in performance. I load the 10mm ammo for my GP100 to the same OAL as the 10mm Mag (1.550) and it gives a clear advantage over any 10mm ammo, but it's still a pretty mild load compared to something like a 41 or 44 mag.
