We had the same problem with .50cal muzzleloaders a few years ago... all the bullets we were trying rarely exited. Where we hunt, if the deer doesn't drop in its tracks (not always guaranteed unless a CNS shot), you may have a heck of a trailing job on your hands... swamp and cockleburr fields... and in some places, swampy woods full of cockleburrs... thick as anything, you have to fight your way through it. It's hard enough trailing them when they bleed good sometimes. No blood trail means a heck of a lot more work (and a lot more time). I won't use a bullet/cartridge that won't give me an exit hole practically every time.Thank you for your excellent reply! I'm too lazy to find a picture of the heart of a buck I killed in '11 who had his heart torn apart by my 295gr .50 cal bullet but also nearly got away. No exit, no blood at all, but he did make it into the frying pan and the back of my truck
I tried a number of different bullets (so did my uncle and cousin) and we eventually found some that shoot good and gave us two holes. We gave the ones that we didn't like away or threw them in the trash.
