First two stages of today's match had me wondering..... Rifle felt... odd. Had to hammer 4 of 10 shots , some twice, in order to get ignition. Figured I'd add a washer as a spacer and solve the problem, at least for remaining 4 stages. No washer to be found in all my goody boxes. What to do? Inspiration struck as I drank some water---the cap from the bottle could be worked easily with my Swiss Army knife. A little flimsy, but it improved things drastically for stage 3--- no more failure to fire when trigger is pressed.
THEN true enlightenment dawned as I noticed one of the many spent 12 gauge wads laying about the area. Just trimming off the base and doing a bit of forming created a 3x thicker and much more robust spacer. A little stiffer lever feel, but total reliability returned and brought needed confidence with it.
Reminded me of a favorite saying of our race bike tuner: "Nothing is more permanent than a temporary repair". I WILL be properly fixing the problem now that we are home.....
