That one was close, but I got another at a good 35 yards. (or more, thought it was out of range, but pulled the trigger anyhow. It fell over dead) Modern turkey hunters like to brag about their 50 yard shots, shooting goose loads, but I have no interest in long shots. If you can't call them in, hunt another day. I don't think a jug-choke will increase range by much. How you load the gun will make the difference. Another thing, a musket is not limited by the length of a shell, as to how much shot you can dump down the barrel. Generally speaking, you are throwing more shot than a modern choked gun. There are all sorts of "tricks" and techniques to improve patterns without a choke.
Not saying jug chokes are bad. If you want one, get one. !!! Just not necessary. IMHO. Other opinions will vary! Kind of makes it weird when you load a ball, as then your ball and patch combo has to go through the choke first, and then is kind of loose in the barrel. Some might say they shoot bare-ball good, but I don't know about that. But whatever you put down the barrel, has to be forced through the choke. Anyhow, just don't spend too much money on a jug-choked gun, or having a barrel jug-choked. !!! Unless you really want to.
