RE: New to me Flintlock
What a nice rifle, sabotloader. Unless it has a custom barrel it is a 1:48 twist which is good for roundball or conicle. Three things to keep in mind are to keep a sharp flint that is correctly positioned. For the fastest ignition use 4-f powder for priming and use a chipped flint instead of the synthetic flints as are sold by TC. The flints that I am speaking of are sold by Track of the Wolf and other supply companies. Also, making sure that your touch hole is clear will almost garentee ignition provided you get a good spark.
Good luck and enjoy your rifle.
