Over on that other forum, you made some disparaging remarks about prelubing the barrel.

-- "Just shoot a fouling shot you says"- well I'm going to take exception with that.
there is more than one reason for prelubing the barrel.
Some Sundays, I get out of church just in time to make it to the shoot, sit down and take my only sighter for the target as my first shot.
Early on, when I had my 40-65 running very well, I did just that, sat down, shot my sighter just over the target, moved down half a target and shot the first shot for score just under the target then moved back to the original setting and proceeded to hit 29 of 29 for the rest of the match.
My quest ever since has been to find a method of "seasoning " the bore so the second shot goes in the same hole as the first shot. (without foulers).
it is doable.
