Hi Norm,
It's just a one day normal practice so no barracks on Friday night. Those shooters taking the challenge (non-ORA members) will have 5 chances to shoot their 1 MOA 10 shot group. For everyone else that attends the practice the usual 2-3 to a target, shooting every other relay without trying to wear out the marker.
A 1 MOA overlay will be used to try to get all 10 shots into 1 MOA. Radio confirmed pass or fail and how many shot landed within the 1 MOA circle. All shots will them be indicated with white golf tees so the shooter can see the size of the group.
