Jrb - I'll go check out that site and do some reading on there. I just shot my buck this evening with my 25WSSM. Shot the buck at 175 yards, it managed to make it about 50-60 yards before piling up. There was absolutely nothing left of the lungs, just a pile of gel in there. I can't figure out why I can't anchor a deer in its tracks with this gun. Out of all the deer I've shot with my 243, I'm not sure if any have taken more than a step or 2, with the majority tipping right over.
But, now that I am done rifle hunting deer, coyotes better watch out. I will be trying this out on dogs here, especially now that we got 6" of snow today!
