You could become a lumberjack?
When I was just a kid in the early 60s, I ordered a Swedish Mauser and a hundred rounds of surplus ammo.
The cartridges had a very long 160 grain bullet. It was fmj with a round nose. The bullets were parallel sided. I took the rifle and some of those cartridges to my Uncles property. I could not find a tree large enough that those little 6.5s would not penetrate.
They left an exit hole only slightly larger than the entrance hole. I showed it to a couple of my friends and they were absolutely stunned by how well it penetrated.
