was looking at the H&R1871 web site and noticed the handi-rifle is being chambered in .50S&W. If we extrapolate the ballistics from the revolver to the rifle we can have a 440 grain bullet at 2000 to 2100 fps. This gives almost 4200 ft/lbs of energy
You'll have some deer waving the white flag if they see their brethren get pancaked by that. Holy Cow. Not sure if a Handi rifle can handle that sort of energy and distribute it well. I think I would want a 9 lb handi rifle for sure
