Well... I guess I'm a loony, LOL!
I made sure I got a .45-70 Handi with wood before they stopped making them. One of my personal faves... Can do what .45-70 has done for over a century, which is take anything on the continent down with simple cast bullets.
And just for good measure I bought an early Harrington and Wesson Buffalo Classic I found in a LGS too... looked unfired, still had the bit of metal in the front sight slot... had to have it, LOL!
And just for the sake of firepower (LOL!) I had to have a Marlin 1895 GS (though I'd have gone with the Cowboy model had they not been out of stock everywhere back after Newtown.)
So's count me in the loonies. .45-70, though "obsolete" really has a lot going for it, because in modern guns you can go from round ball to trapdoor cast to really hot 300 gr. jacketed, all in one gun.
Some folks call it "mild to wild".
But yes, my .30-06 is probably an overall more practical thing. Especially for the long shots. Much flatter trajectory.
I agree, for *most folks* the budget bolt guns make more sense.
But, being a cast bullet fan, the .45-70 is a great choice since the range of bullet weights is so broad, and the brass is still available. Probably dozens of powders that work well too.
