Crazy Ed,

Patched round ball can work fine in a fast twist barrelif the load is fine tuned. I have had good success and accuracy with up to 80 to 90 grains of 777 in one of my inlines and a PRB. The secret seems to be how tight the patch is and ballance that with the correct powder load. For my gun I had to go to a .020 to .022 patch and a .490 ball. It is very snug going down but shot sub 2" groups at 50 yards. I haven't shot that load through my chrono yet but I would guess it is moving along quite well. I am going to do some more testing once the hunting season is over and will report back on the results.
