From about a month our gunshops start to sell Hornady international in 9.3X62 with 286 gr InterLock® SP-RP bullet. i like InterLock® SP-RP bullet in my rifle so buy box of factory ammo and put them otrough magneto speed. This is data what I get&
Gun: CZ 550 medium lux 9.3X62, 60 sm barrel. Temp.: 13 ℃ degree celsius wind: 2.5m/s light rain
av. Vo = 2231 fps/680 m/s chronoed with magneto speed. On box is written Vo= 2368 fps/722 m/s. Factory ammo COL was 3.133`` I just wonder about this 137fps/42 m/s diference?
