I have the same rifle. It is a 1-66 twist I believe. Mine shoots 90 grains of powder and a patched roundball excellent...

thats an awesome deal. i have the flintlock version. i also snagged a new 21 inch barrel off ebay. as a carbine its carries nice but looks funny. CONGRATS!
Jeep, I'm almost positive the PA Hunter had a round barrel. But I've been wrong once or twice before. It did come with a slow twist for round balls. (either 1:60 or 1:66) My friend had one and he used it quite a bit with good success. His shot buffalo ballets good with 100 gr of FFFg.
