On a happy note: LWD has the "GT Hole" reamer in house and ready to go. If anybody out there has the stomach to read through all these posts I guess they should be rewarded! I am more than happy to offer a chamber ream for free. All you have to do is ship us the barrel and include a simple note requesting the GT Hole. We will knock it right out and get it turned around within the next couple days.
If you have any doubt regarding your load fitting the chamber please do the SMART thing and include a couple dummy rounds so we can verify.
