For a long time now, I've thought of giving it a try - 7:1 you say, eh?
I'd likely use the .69 as I know it's accuracy & would, of course, put on a higher bead or aperture front sight and likely mount a tang-aperture as well.
I've oft times wondered just what that old girl will give, accuracy wise with real sights, instead of what some writers have called "Good for 25 yards only".
They didn't have ANY idea what they were talking about, in my honest opinion.
This sounds as it it might just be a good test for next spring, before the bugs get bad.
So!
Shooting dry patch & cleaning between shots:
Shooting thin wet patch and cleaning between shots, the system some guys say works so well for them:
What about thin wet patch and cleaning every 3 shots - another method I've read about? Do you start a new group with that 1st clean shot, or just use the 2 dirty shots for group?:
Using normal wet thick patch with no wiping for control groups:
With so much cleaning, it will likely take a full weekend to perform the test - not used to that.
