I shot the 10mm XTP both 180 and 200 in sabots and a muzzleloader . I have killed about 20 or so deer with the combo. Only deer I didn't recover was when my scope was off and I had a low hit . Had blood but it made it to private property and I had to stop the recovery. Most deer drop in there tracks few that ran didn't break the 40 yd mark. J.michael

Back when I was shooting 10mm, I had good results with the 180 XTP and AA9 powder, around 13 gr as I recall. Never took it hunting so I don't know about terminal performance.

Power Pistol is what I always load for fullhouse loads.

I do shoot the 10mm in a Ruger 1911. Blue Dot has been consistently the most accurate powder I have tried with both 180s and 200s. I shoot mostly 180gr X-Treme heavy clad bullets, but did shoot Hornady XTPs in both weights for accuracy testing with "hunting" bullets. I have had great results with Power Pistol, Unique, and Longshot, and excellent results with Blue Dot. I cast a 200gr FPGC bullet from an NOE mold, but haven't invested nearly enough time to say that I have found the powder combination it likes best. I haave found that 10.4 grains of Blue Dot with the 180gr clad bullet gives excellent accuracy, and even gets some expansion with the flat nose. I am a 45 Colt guy, but I do feel the 10mm is a great all-around cartridge. In factory fodder, the Remington 180gr "practice" ammo is inconsistent and gives great, and poor accuracy, DoubleTap is excellent in the 180gr Bonded Jacketed bullets and their 230gr hard cast, Sig Sauer 180gr Jacketed is what the pistol seems to like best as far as defensive type ammunition goes, but the Hornady 180gr XTP ammo gave very good results as well. I have yet to try and of the Underwood ammunition, but have read good things about it, but it was mostly from people obsessed with the most speed possible from the 10mm, I am an accuacy guy first and foremost. One of these days I will get around to trying some Sierra jacketed bullets. The only thing that I do not care for is the bullet seating, it is very critical for the Ruger, it likes the bullet to be seated from 1.52 to 1.57 inches OAL, my Dillon Dies and the X-Treme bullets don't always make this an easy task, but it is well worth it when the shooting commences.
