My choice would be my old Savage 112 from the late 70's, caliber is 220 Swift.
A Burris Sig. series 6x24 target scope w/1/8" clicks, harris S bipod.
Several years ago factory barrel was replaced with a Douglas 26".
The factory trigger wore out and was replaced with a rifle basic.
Handloads I use IMR 4064, CCI primers, Winchester brass, nosler 50 gr. bt.
Brass is neck turned, neck sized, powder charged weighted, bulled seated.
The farthest Groundhog so far is 715 yds., checked with a Leica 1200 rangefinder.

I'm not a Swift fan but that's a long shot on a hog with a .22cal rifle!
