Cayugad,

This was my thinking: is it possible a combination of a .490 "bullet" with patch might produce better accuracy results ina slow twist gun than your basic .503 maxi-ball? I question the expansion of maxi-balls into the grooves of slow twist guns. Not that some doesn't happen, but I doubt the spin achieved is anywhere close to that of a round ball, partly due to added weight and therefor added slippage. Further, I suspect there is material damage to the all lead conicals which might be eliminated as the patch would take the abuse and drop away. Similar to employing a card or wad, but the patch would, I think, impart far greater spin. Dunno.
