I have been having issues with my 40 minor Glock load. I was loading OAL between 1.1250- 1.1300 with brass I bought on line and plated and lead bullets. Everything was doing good then I started using range pick up brass and only lead bullets. Started to get several that wouldn't fully chamber or were sticking at ULSC so I got a EWG 7 hole case gauge. My old clays load (before I changed brass source) all gauged just fine but my new loads (e3 load) failed about a 1/3 of the time with bullet in. Those that failed passed about 90% with bullet up.
At yesterday's match I had a couple of stoppages with the KKM barrel so I changed back to my Glock factory barrel and only had 1 sticky round at ULSC but didn't have to bump the slide any to get it into battery. So today I took the ones that failed and took my seating depth down to 1.1175-1.1200 and turned the Lee FCD down a little bit and 2/3s of those round passed the gauge bullet down. The 1/3 of those that failed after the adjusting measure the same OAL and when I measure the case diameter at different places along the length of the brass nothing measures larger than the holes in the gauge.
If I haven't totally confused you all as bad as I'm confused and lost as to why I get some that wont function in the gauge or the barrel when they measure out the same, does anyone have any ideas I can try?
My reloader is an old Lee turrent with Lee U sizer, expander/powder, bullet seating and then Factory crimp die.
