Seems the Italians don't want to know about English 7 1/2 shot size and only load 24 gram in their own version which equates to English 7. One Italian maker loads 7 1/4 shot Italian.
Took some of the latter to the pattern plate and got a shock at the lack of pellets in the pattern leading me to believe that much tighter choking required to avoid the holes which has a knock-on in the accuracy required to break those OT targets.
It doesn't seem to make much difference at the very top level but further down the pecking order maybe an ounce of English 7 1/2 would help those who like to shoot OT but don't have World Cup ambitions.
