I slipped out between rain showers today and fired the first series of five shots from the bench. Weather conditions were good except for being a bit damp. The temperature was 54 deg F, baro pressure 29.54, and a wind of 10 mph from my right rear.
I decided to begin with a load that works well in my other 20 gauge, 75 gr FFg and a .600 ball. I used shotgun wads, over powder, lubed cushion, ball, and over shot. I'll try other things, PRB, tow, etc, on a drier day as well as varying the powder charge. I recruited my wife as photographer and so was able to get a photo of the gun at ignition. She set the camera to take photos at 3 frames per second and when I did a countdown she hit the button. The result is this photo.

If you look closely you can see that the smoke from the pan has not started to dissipate and there are flames coming out of the muzzle. In other words, ignition is fast! Fast ignition does wonders for accurate shooting. You may also note that I'm a lefty and the lock is on the right side. A friend asked me if the flash from the pan causes me to flinch? My answer is "no". I close my right eye when aiming and the commotion in the pan is no closer to my left eye than it would be with a left handed lock. Besides, I started shooting BP guns in the late 1950's and I never saw a left handed lock until I was in my 30's. By then it just wasn't a problem.
I fired a series of five shots with the above load. I wiped the bore with a patch wet with Dutch's Moose Milk between shots and followed that with a dry patch. I pick the vent after wiping and again just before priming the pan. I experienced zero misfires. Here's the result from 20 yards. I freely admit that I'm probably the cause of the vertical stringing. I suspect that because I was hitting low I was subconsciously raising the front sight for subsequent shots.

That was it for the day. I'll obviously need to file down the front sight but that will wait until I've completed load development. Suffice to say that I'm happy with the gun.
