This is my eighth ever grouping. The sighting is a little off and needed adjusting, but it's a half inch group (i.e. pretty good) - and at the moment I'm mostly concentrating on the grouping. I'm really very pleased with things so far, it's good fun, and it's something I appear to be taking to!
My largest grouping to date is 1 inch, all the other seven are less than three quarters.
