Both are/were common with Blackpowder and cast bullets.its not uncommon to see them at matches. Mostly smaller manufacturers, but they are catering to a smaller crowd.Agreed I like choke if we can get it. I like gain for that reason
Ron Smith, RKS barrels out of Canada does left hand, choked, gain twist. Borchardt Rifle company is another that offers choked barrels.
I know there are others.
Krieger May offer a choked barrel. There was a run of barrels some time ago that were specifically for Blackpowder. Krieger offers “Henry rifling” and some were sold as having a choked bore. I don’t know if the choke was done at Krieger, or after the fact.
As I said before, I have a couple left twist barrels and the biggest problem is switching back and forth. More so off hand, and critically when making windage adjustments/calculations.
