Its on the SP-01 Open 9 racegun. the one with the threaded barrel I hand fit at the kitchen table for 2.5 hours around midnight one dark rainy evening a in 20..something...
It shot great at first then spun out of time. I tried a few things and a few other things and help from another local builder. Still out of time.
This time I am trying the locktite primer and gobs of high temp 272. I suspect it will shoot 47 rounds or less of major, but we will see. Its been a fun journey either way. Of course I'll first try a few normal minor PF rounds. The funniest part of the whole thing is that the comp is made for a *gasp* Glock... I fixed that part...
