Been pondering this for a long time ... along with you all.
Wonder if I have come up with a fairly good theory.
I along with others can get 2 shots that almost touch at say 45 yards. Then the 3rd shot goes its own way ... even off a bench rest. I get open groups with 3 shots of around4 to 6 inch at 40ish yards consistantly. Tight patched .595 , .600 ball over the powder and wad over the top, powder charges from 60 grains 3F to 90 grains and 70 grains 2F up to 100 grains. Wads between powder and ball as well as ball right down on the powder. Nothing changes much between any combo.
My theory is such. Might it be barrel flex what with the thin long round portion of the barrel. Might the heat of the thin barrel begin throwing balls in a very short time ... say within 2 shots?
I wonder if a pretty rigid heavy barrel would give better accuracy with the smooth bore. Say a 1.125 inch breech diameter tapered to a 1 inch at the Muzzle. Maybe even heavier barrels or shorter more rigid barrels.
There is my spewage. My fevered wonderings have now been released. What say yee? Am I batty as a loon or do ya think
my pondering has any merit?
