Well, you can get you one of them plastic and aluminum tinker-toys, or you can get a battle rifle. The former fires a cartridge considered adequate for ground chucks, wood chucks, and other small vermin, but is considered marginal for deer, except with the very best bullets and absolutely precise shot placement, and even then several states in the USA prohibit its use on deer. Or, you can get a battle rifle in 7.62 x 51 mm, which fires a cartridge that, in its commercial guise (.308 Win), is considered adequate for any game in North America with the exception of brown bears. Hmm, poodle shooting cartridge, or big game cartridge? I know what I like.
