I just took a measurement of 1.644" OAL with a W209 installed
Is that with your firing pin bushing screwed all the way in?
And when you close it you are getting a snug fit against the primer???
You are out of CCI-209m's correct? I wonder what that might measure?
I also have to admit i can not figure out why when you drilled it out it stopped shooting unless you lost a seal at the primer or in the bore. Really and honestly that should have helped you...
