Put a Vortex CF2 6-18 on the TR last night, adjusted the Accutrigger and tried it out today.
Average of three 5 shot groups:
CCI Standard Velocity .775"
CCI Green Tag .401"
I did not encounter the first shot flyer issue today even without replacing the bottom metal. When I removed the stock to adjust the trigger I found that the front barrel pin was digging into the stock. I relieved the stock around the pin so that could have been causing the flyers.
