Success today.
I’ll write a detailed post tomorrow. But, the conclusion is that this barrel must be well FOULED to shoot. 600 yard groups shrunk and Velocity ES and SD’s dropped as the round count went up, SD’s got down to single digits.
I’m considering not cleaning the bore at all for a while and see how long it takes for groups to open back up again.

Sometimes we must persevere in our root cause investigations and tests to find out what works and what does not.
Shot my best score at 600 yds today with the T. This rifle wants to group, just takes a bit of persuasion. If I had set the proper caliber on the monitor, this would have been a 99-4x. It’s set for .223 rather than .30 Cal. I know this rifle can be a winner in the Vintage Sniper Matches.
