Go to to the range to sight in and put around 100 rounds through it. This will give you a nice fresh lawyer of fouling . . .
Now that's one of the funnier typos I've seen in a while.
I'd be quite happy if I could get the rifle to shoot within one minute-of-lawyer.
Seriously, though, thanks for all the discussion on this. Very informative for someone like me who's basically been a pistol shooter for some decades.
