I sometimes wonder how a rifle would shoot with a tapered throat,
one with no rifling for the first half inch or so just a tapered cylinder like the revolver uses.
Not well at all. I over throated a 223 bbl in the way you describe. It was a spray & pray affair afterward. I tried a zillion combos and came to the conclusion that I ruined it, not that it was much good before. I throated it even further just for fun and it only got worse until it wouldn't group even at 50yd.
I have 270 with a fire worn throat. It's loosing accuracy quickly. Maybe if you had a forcing cone just past the smooth throat? I dunno.
