I just got back from Mi. where me and my bud went hog huntin'. We both used our 20's his being a 3rd gen with adj. sites and I used my 1st gen with fixed just 'cause haven't kilt me anything with it yet. Both are with factory barrels etc. We decided to use diferent loads to see how they perform on the hogs. He used 155gr Gold-dot from GA. His hog ended up wheighing 200-225. His first shot hit right behind the shoulder and actually knocked the pig over. I couldn't beleive it. The pig got up and he whacked it again as it ran off. It ended up running about 40yds total and crumpled. The bullets didn't pass through but when we gutted it there was plently of lung mash to go around! We should get the bullets back after we pick up the hogs from the butcher. I used the 200gr XTP from T.A.C. My hog ended up being over 300lbs with huge a**-ed tusks. My first shot at about 20yds hit right behind the shoulder but the big porkbeast barely flinched as it started to run off. At about 35yds I touched off again anchoring the beast as I nailed him right behind the ear exiting out his eyeball. After looking him over we found that the first shot passed through exiting further back completly destroying both the lungs and liver, it looked like it expanded nicely also since the exit hole was about the size of a quarter. I was amazed I got a total pass through on a 300lb hog! These darn 10mm's continue to amaze me. I was real impressed with how both these loads stomped pig a**! Can't wait to do it again!
