Do you live in the US? If your state doesn't require background checks for private sales, you could go somewhere such as armslist. (My state does, but yours might not). Or you could get a .50 caliber muzzleloader and use .50 caliber hollow point bullets. I was initially going to do that, and it would've worked if I did. I also no next to nothing about guns, and it was easy to figure out how to use the gun.
