First of all, I had one, back in the mid 70's. It was a .36 and it had a wawawawawawawawawawawa-type bore - as Hall was trying to make a deep grooved button'd barrel. The metal would move out of the way of the button, then move back at least part way, giving a surface you could feel- tight/loose/tight/loose etc down the tube - sort of rippled like sand on a shallow angle beach - you could fell it with a tightly patched ball or even a patch on a jag. TC's shallow rifling barrels were similar, but not as bad, still difficult to look at through the bore at even a 60 watt bulb.
Question is this - did Hall Sharon cut rifle barrels as well? Reason for asking - I'm told my new .32 Tenn. rifle has a Sharon barrel. The rifling appears to be about .008" deep, has narrow grooves and wider lands, opposite what I've come to think is best. I cannot feel any irregularities inside the bore - it 'feels' to be a cut rifled barrel.
