I completed the tests with my MP5, 9” barrel for velocity.
Ran 65gr LeHeigh defense, loaded to 1.100 and a federal small pistol magnum primer.
All powder was Ramshot Silhouette using the load data from LeHeigh defenses website from my 550b.
SD seems somewhat wide on the rounds we ran, but I don’t think it was metering super well.
Pictures of the cases will follow on Sunday, however we saw no pressure signs from any of the charges.
9.0gr powder 1939, 1930, 1968 avg 1945
9.3gr +P powder 1962, 2020, ERR avg 1991
9.5gr +P powder 2032, 2061, 2036 avg 2043
9.7gr +P powder 2030, 2040, 2074 avg 2048
9.9gr +P powder (max book) 2098, 2087, 2100 avg 2095
