Took my smoothie out today for the first time in about a year. Old age and arthritis, and other problems wont allow me to move to well any more. This gun has never failed me in the past. It's an early Virginia smooth bore. This was my first build, I bought it from Jack Garner. It only cost $400 so that should give you an idea of how old it is. It has an early Virginia lock by Jim Chambers. I tried Skychief's load, first time with 1F . I took about 3 tries to get it to fire, I used a brand new English flint from Track. I noticed that there was at least a quarter inch of space between the edge of the flint and the frizzen at half cock. This fired reliably last year, now it was taking 3 to 4 tries to get it to fire. I prime with 3 f like always, and I notice that the edge of the flint is chipping. One time when it didn't fire I noticed tiny flint chips in the pan with the prime. Is it time to reharden the frizzen? The worst part of this is that the pattern at 25 yds. makes the squirrels in my back yard in trouble!
