big country, I forgot to mention that I reamed my cylinder out to a true.4525". One of my main gipes about Ruger is they bore the cylinder on there .45's smaller than the bore of the barrel and this really hurt's performance. (gases going by the bullet) I have seen a few .44's this way, but not many.
Maybe my Chronograph is off, but it is off for all guns involved so I guess it would be relative.
Good Luck
