My M&P 40 went 4000+ rounds without being cleaned. Only issues were one piece of remington UMC 180gr which just didn't go off. Took three strikes to make it go boom. I had 4 squibs due to my powder drop having issues. I also had one high primer, also my fault. The gun even fired and cycled some 110pf ammo i made without issue.
raz-0 -- did you ever put any lube on between the first shot and the last?
The rules of the Challenge set up a procedure for dealing with misfires. However, one stoppage in 4,000 rounds means obviously there was some 2,000-round run without a stoppage. Still, we have always run the Challenge as a specific intended period of shooting, so just having 2k rounds of trouble-free service sometime in the past hasn't really qualified.
While you'd have to report the squibs, squibs are clearly not gun-related stoppages so they wouldn't count against being declared a success.
Not surprised your M&P ran so well, but a 110pf load? Sheesh! Were you using the stock recoil spring?
