Greetings,
Daryl,s comments from Central BC. are right on the mark. I should have qualified my comments about wiping between shots. When I am at a match or testing at the range, I religiously wipe between each shot. A clean patch damp with Black Solve is stroked in the bore 3 times on one side and then 3 times on the other side. My interest is in obtaining
MAXIMUM ACCURACY by keeping the bore in a consistent condition from shot to shot. Hunting is a different situation, although if circumstances allow, I will wipe and DRY the bore with a 2nd clean patch. Barrel rifling styles make a difference when reloading a 2nd or 3rd shot without wiping the bore. Barrels cut with wide grooves and more narrow lands are easier to reload if not wiping between a 2nd or 3rd follow-up shot.
My 58 caliber unlimited class bench rifle with a 1-72 twist
requires a minimum charge of 180 grains of 2ff powder to shoot match winning group at 50 and 100 yards and up to 200 grains for the 200 yard event. This with a .575 diameter round ball of course. With this charge, a common nipple burns out in 10-20 rounds, therefore a sealed ignitor system is used instead.
Most of the flint-lock shooters I know use 40-45 caliber with 3fff powder for the faster ignition. I shoot mostly 50 caliber at the matches and hunting. At the matches, 3fff is used because it gives more consistent ignition and accuracy. particularly on a damp or rainy day. Top load in 50's is 80-85 grains of 3fff. For hunting, 80-100 grains of 2ff is used.
If I lived in country where game bigger than white-tail deer or wild hogs might be encountered, my caliber of choice would be nothing smaller than 58 caliber with a 1-70 or 1-72 rifling. The slower the rifling twist, the higher the velocity is reguired for accuracy. A big ball at 1700-2000 fps is a good killer. One of my shooting friends(now deceased) had a 62 caliber bench gun and it was impressive.It is a matter of record that the Hawkens brothers made on special order at least 2 62 caliber rifles, and the 58 caliber was not uncommon.
