You are both right, but it does seem worth the effort at not much cost, you could get lucky or even have an acceptable grouping....acceptable is of course another subject.I do seem to remember one of our links where a guy cut his barrels back to cylinder and shot round balls into a 2 to 3 inch group at I think 50 yards. to me that is acceptable.Daryl knows more about all of this than must should, so his word is my best guide......I'd still like to try it to see what we get.
