Another superb day ... thank you Mark and all the other officials.
Some may have seen Anne with a Haenel Schmeisser bolt action gallery gun (c. 1933) on the plinking range after the shoot. It fires 4.4mm, 7.3gn lead balls and a chrono test at home shows it has a mv of 175fps for a heady power level of around 0.5 ftlb. A swift calculation suggests that in the absence of air resistance it would have a maximum range of about 960ft. I have not worked out the max range with air resistance but guess it would be around 300 ft ... if anyone can furnish the necessary equations, let me know.
Cheers, Phil
