The "Ballistic Tip" line comes in two flavors, one for "varmints
" and one for "big game
." The "Big Game" variety had a thicker jacket for good weight retention, the "varmint" variety didn't. Some folks didn't mind using the "varmint" bullets on big game, and got the "explosive" results that 5R describes.
Like I wrote before, all bullets are lethal, there is no question that shooting stuff will kill it. As far as bloodshot meat goes, if you want to get more meat then use a bullet that holds together better than a match bullet.
