Rarely do I gun hunt anymore but if I do it is either my .44mag pistol or my Thompson Center Impact 50cal ML. The Impact is a freaking tack driving - simple - cheap ML.
TC Omega 50 cal with Barnes 250r T-EZ Sabots with 100r of Triple Seven. It has never failed me and I can punch the center out of a target at 100 yards. Love it!
TC Hawken flint lock round ball. I also picked up a TC Triumph that I sighted in and then took my bow out in the late season. It looks good in my safe anyway.
