Ever so slightly off-topic, but does anyone know what the military loading was in the 1960s & '70s? I have a T-Series Browning Hi Power that seems to be shooting low (@7 yds.) with my 124 gr. Frontier bullets and I'm wondering if the sights were designed for 147 gr? Could be due to other factors, of course, like the shooter!

Military 9mm ammo is 115 grain.
