I took the Big Boy and the SmokeWagon to the range again today. I planned to alternate between the revolver and rifle, starting with the revolver. I shot 5 rounds of 125 JSPs (H110 - WSPM), then 5 rounds from the rifle.
Next, I switched to five rounds of 130 FMJs (Win231 - WSPM) in the revolver, but the last round didn't go off. I took it out, looked it over, and thinking it looked OK (no partial dent in the primer), I loaded it again. It still didn't go off, so I emptied the gun and inspected the firing pin, which (I noticed for the first time) moved around in the hammer. I thought it was broken. I put the unfired round in my Henry along with five others and all six went off, no problems detected. Sadly, I put the SmokeWagon in it's bore stores case and shot the rest of the 100 rounds from my Henry, five at a time.
When I got home, I called Taylor's & Co. and talked with the gunsmith, who informed me that the firing pin is supposed to "free float" and the movement is by design and is called a "free floating firing pin". I learned something new -- again. He said if I shoot it again and it still has a problem to call him back, but he suspected the primer was likely the culprit. So, we'll see. It's still under their warranty.
Regardless, because of that, I have just two targets today instead of four. One with 45 rounds of JSPs and one with 46 rounds of FMJs. As usual, I shot off hand, standing at 75 feet. The Henry has a Skinner Peep and a stock front sight.
I had fewer flyers with the 130 grain FMJs, as you can see.
