Looks like now is my turn to call you all for a brainstorming, next couple of days I will not have time to take the Impact apart so I hsall have a chance to pin point theoretically the source of the problem.
Last week at my shooting range I noticed the speed started dropping like 100 fps and more (according to my radar, which is pissing me already for some time).
My first taught the C1 got loose. Toke it apart yesterday, not the C1.
OK, maybe the Reg. Toke it apart that one too, cleaned the gunk from the airpath (last time I filled my SCBA I noticed that it sucked in some moisture), replaced the new orings, re-lubed, gas it up, it was holding air over night. Washed and polished the liner for a fresh start.
Today range time, all started promising speed about 880's, then after some 2-3 mags the speed started raising to 920ish (ok maybe this much need for the liner warm-up) .
4-5 more mags reload and the speed started loosing again down to mid 770.
And in mean time my radar is playing crazy, no numbers probably 90% of the shots, and what is showing the numbers all over the place.
First, I would throw away that FX radar, but teach me for a real convenience. If I replace it only something else again = portable and pocketable. Researching now as we speak what else my be good enough to consider (no chrony style, I had many of those during my archery time, not going back to dinosaurs. I feel kind of sorry why I didn't got the Labradar instead, but I was just way too cheap to spend a grand for the machine that steel needs a pile of cash to make a complete kit...
OK, back to OP.
Not leaking, not the Reg what else may be involved to have a speed erraticall (other then the radar, again), lead deposits in the liner? that is easy to wash.
My .25 Impact is heavy ported and custom springs (hammer and valve), the valve poppet is peek...what else could make the huge speed swings?
