He could try a shotgun with slugs or buckshot.
There are a couple of places here in GA where I am not too comfortable hunting with my 7mmRemMag. So I'll opt for the Winchester model 94 (.44Mag w/ hollow points) or a Remington 11-48 12 guage shotgun with 00Buckshot.
In some part of Maryland that's the only thing you can use. (slugs or buckshot).
Wondering how the .44 gets the job done.
I've been toying with getting a lever in .44 or 35 Rem.
(why I don't know as I don't hunt, just have the urge for a big bore)
