Hello Cayugad. On reading your post...I had to think about a deer I shot 3 yrs. ago with a T/C Firehawk in .58 cal. with a patched roundball almost EXACTLY the same scenario but the deer was quartering more towards me. Anyway, same thing...about a 45-50 yd. open shot and the deer did a 180 like it had never been hit. Peeled out and ran back into the thick woods out of sight. I climbed down, went to where it had stood and not a drop of blood...just the tracks where it had spun around. And I don't care who says I'm nuts...I could smell that the deer had been hit...that's right..it smelled just like it does when you open a deer's body cavity. I began to follow the trail it was on and found blood about 40 yds. from where I shot the deer,but nothing significant. I continued to follow about another 70-80 yds.with minimal blood trail and stopped to survey the situation...about 40 yds. further the deer laid in a heap in one of those little "divots" that dot all hardwood hillsides. I had taken it cleanly at an angle through the left lung, caught a small portion of the rear of the right lung and the tip of the liver. I'm not dissing round balls but I wasn't impressed with the blood trail...BPS
