Part IV: Most unique, odd or rare cartridge you have taken game with.

[Whaler17]

BR7mm, Thompson encore, tack driver @ 500 yards , if switched over to pistol @ 100 yrds, all in the bull eye

I once took out a raccoon with a 20-‘06 Lincoln. Does that count?

When we were kids, my cousin and I were out and about with our shotguns. A doe ran into the field about 40 yds ahead of us and just stopped. He slowly ejected the 20 ga birdshot shell from his pump, took out his knife and cut the shell through the wadding, loaded it back in the gun and let the hammer down on her. It looked like a slug at the entry with nothing out the other side. When we gutted her, there was a clean hole on the one side, vitals were non existent, and the opposite ribcage was littered with bb’s.

Cut shells are a serious recoil generating somewhat dangerous toy

I don't own any odd caliber so I'd have to go with a black powder rifle. Lyman great plains rifle. 1:66 twist. Round ball with a spit lubed patch with double f black powder and a number 11 cap.

Edit. Back then it was open sights and sidelock only. Charge was 90 g as most powder horns had a 30 g spout.
