RE: whats wrong with flintlocks???.......
I've just gotten into the flintlock scene. It is a .50 caliber T/C Hawkins. After some good advise from Roundball, I had Thompson Center replace the entire lock. The ignition time now is excellent. I am using a amber french flint and with 4f Goex as the primer, it is as fast as most of my cap locks.
I have been working up a load but so far 65 grains of 3f Goex seems like the best with a roundball. The rifle also seems to like Buffalo Ballets and I have even shot a few maxiballs out of it with good results although I have not tried at a distance yet.
My next rifle will be a custom made flinter. I want at least a .58 caliber but would actually like something bigger then that with a roundball twist rifled caliber. My .62 caliber smoothie just will not shoot a roundball accurate enough at long distances for my standards...
