I'm seriously considering building a 44-77 and am wondering about the barrel dimensions i.e. bore and groove diameters. And what barrel maker makes such.

BIG OR SMALL I LIKE THEM ALL, 577 TO 22 HORNET.
Modern barrels are .438" X .446" typically. Not sure who is making them now other than Shiloh.
Green Mountain still advertises them. I think they have a 16” rifling twist, versus the 19” twist of the Shiloh barrels.
On the Historic Shooting Forum, the late, great Distant Thunder wrote up a lot of his experiments with the .44-77.
The twist on GM barrels is 17", They are .438/.446. They will shoot quite well. Depending on your use you will want a heavy barrel. A #3.5 barrel on a Pedrosoli rolling block, 30" long will give you a rifle in the 10 1/2 pound range.
You will need a reamer with about a .436 diameter pilot. This is what my smith told me when he measured my barrel in prep for me to order a reamer.

Shiloh is 438 446 and so is my green mountain and from advertisements and feed back from folks that have used them so are Kreiger
Long range rules, the rest drool.
