Thanks for the reply John - wasted shots are a massive no-no for load testing - what calibres did you use with it?
did you use the recoil trigger?
incidentally, when I tried to buy a Labradar off MK machining at same time as the mount (based on cost given transport was a flat fee) the guy I spoke to said:
a, can’t sell to Europe, he did not know why but this thread has enlightened me on the power levels and EU rules
b, not to bother as the magnetospeed work better
