When I was growing up, if one managed to avoid a bad event, we called it "jumping over a snake." Nowadays, various professions have fancier phrases like "sentinel event" or "near miss," but it's still the same thing. I had a similar experience last weekend. It was only 7 days before my last prairie dog hunt of the year and I was doing some last minute sighting in. Things had gone well w/ the 22 LR (Tikka T1x rifle w/ Spectre 2 suppressor)) and my handguns: 20 VarTarg (Howa Mini-action w/ McGowen barrel) and Nosler Custom Handgun in 22 Nosler. The only gun left to shoot was my Remington XP-100 handgun in 223 Rem Ackiley Improved. It was getting really hot so I wanted to finish up. Imagine my surprise when my first fire forming load failed to go off when I dropped the hammer. In addition, there wasn't even a mark on the primer. The gun had never had a misfire. Also, I'd already shot 70 rounds out of the box of 100 w/o a problem. I tried a total of 5 rounds and the primers were untouched on all of them. After doing a lot of research when I got home, I suspected a broken firing pin or firing pin spring.
I'd never broken down the XP bolt before so I consulted a number of YouTube videos the next morning. I noticed the bolt lift was very stiff, kind of like what happens after shooting a load w/ high chamber pressures. The videos said to partially cock the bolt and insert a nickel in the end of the bolt to keep the spring partly cocked.. The first thing I found was that my bolt needed a penny, not a nickel. After taking the bolt apart, it looked like there was a fleck of brass inside the body of the bolt near the firing pin hole. I couldn't remove it w/ a Q tip, but it washed out after flushing it w/ copious amounts of carburater cleaner. The firing pin assembly waa dirty, but otherwise ok. After reassembling the bolt, I dropped the hammer on four primed pieces of brass. Happily, all four ignited.
I went back to the range to shoot the 223 and was very pleased. I shot 3 groups, each w/ 3 shots. The first group was shot without the suppressor, the second group w/ the suppressor and the third group without the suppressor. I made a small horizontal adjustment on the scope for the 3rd group, but you can see the suppressor otherwise had no significant effect on the point of impact. Next I shot 3 shot groups w/ 3 different 50 grain bullets (Speer soft point, Speer TNT and Hornady SX) and 2 different powders (Shooter's World AR Plus and Accurate 2200). I really like how this gun shoots different bullets w/ same weight to the same point of impact.
So everything turned out ok. All my guns are working and shooting accurately. Now I'm hoping the prairie dogs will cooperate on the hunt.
