For folks who prefer a semi-auto, Ruger once made the M44, which was a .44 Magnum semi. It's the rifle that put Larry Flynt in a wheelchair.
I had one of the Rugers, I wish I had never sold it.
Great light weight rifle, with plenty of power.
Oh well.
The Deerslayer?
That was the rifle used by Mark Essex in 1972.

I remember watching that shootout on live tv.
Interesting note: Mark Essex used a .44 magnum rifle, but one of the men who was shot and survived said they surgeons pulled a .30-06 bullet from him. It was speculated there was other shooters.
