I use this brand for different situations and I am 100 percent convinced and completely trust it for effectiveness. Underwood 140gr Extreme Penetrator 1500FPS MV/700 ME, Underwood 140gr Controlled Fracturing Hollow 1500FPS MV/700 ME, Underwood 155gr XTP 1500FPS MV/774ME ,Underwood 180gr XTP 1300FPS MV/676 ME ,Underwood 200gr Hard Cast Flat Nose 1200FPS MV/703 ME . I carry 4 mags hunting Deer 155gr XTP AND 180gr XTP and 200gr Cast for Hogs or if Bear gets pissed for attitude adjustment!. The 140gr are for the range and protection. Depending on you pistola and length of barrel I would choose Underwood 180XTP all around if you only want to shoot deer and meat hunt. For a challenge the 155gr is more than enough to take thin pelted Animals like deer for longer shots. Underwood is by far the best for the money and quality (Less FTF & Packs a punch) Some folks will swear by Double Tap, Cor Bon, Buffalo Bore and still prefer UNDERWOOD . The cool thing about the 10mm is that it is offered on a 1911 or small easier to handle frame and weight. Other options exist in automatics .357/.44/.460 Roland etc. but some of us just prefer 10MM. Take some time and read the reviews on the Underwood Web-site 10MM ARE AWESOME WEAPONS . You will enjoy shooting yours. Pick one that has good sights and trigger and can handle high case pressure. The DW 1911 Bruin 6" slide is on my Bucket list. Good hunting PRATICE,PRACTICE,PRACTICE=Confidence
