Amendment 4 Question 1 Page 51 (paragraph 3) of the solicitation states—

The velocity test for shotgun ammunition will be performed utilizing a Universal Receiver, a SAAMI specified test barrel and an Oehler chronograph. Five (5) strings of ten (10) shots will be fired. The nominal mean instrumental velocity for each shot shell will be measured at ten (10) feet from the muzzle Can the Secret Service provide more details about the instrumentation used to obtain buckshot velocity? Is there an Oehler 57 or equivalent start screen at 1.5’ and stop screen at 4.5’ from the muzzle measuring the leading pellet velocity? Or does the instrumentation use inductance coils for a start and stop signal?

A: First screen is 5’ feet from muzzle, second screen is 15’ from muzzle, thus creating a 10’ instrumental velocity reading. We use the Oehler Model 57 sky screens.
