I dont have a lot of info to say about the SW's, this was the first year that I have ever used them. I do know that they are a very accurate bullet, my rifle shoots them extremely well. The only deer that I have taken with one was this fall. He was a 156lb. field dressed buck that I shot broadside at 50 yards half way up the chest. The buck spun around and went back the way he came and travels at the most 40 yards before dropping. When I walked to the spot he was standing, laying on the ground was a 2 inch piece of lung, the blood trail leading away was simplyimpressive, blood poured out both sides of this buck. He was shot with a 250grbonded SW. I rarely drop a buck in his tracks most travel a few yards before giving up the ghost.Most of theones that have dropped in there tracks were either hit in the spine or front shoulders, but these are shots that I only take when i have no other choice. I dont want to waste any more meat than I have to. I didnt realize there was so much debate over muzzleloading bullets. The old buffalo bullet that I used for years worked great. The only deer that I have lost with one was my fault, a classic gut shot that I made when buck fever set in on me. I knew when I pulled the trigger Ihad screwed up.In my opion if you blow thru both lungs= dead deer.
