Milsurp or reloading can easily be decided on you shooting rate, 500 rnds a year means Reload.
the start up cost for the press and dies and the time consumed in the manufacturing are all things to weight in. For myself I only shoot 100 rnds in my m48 a year on average and bought near a thousand surplus rounds through the EE and online merchants. The gun shows in the Ottawa region have been very poor in findings and when it comes to price they sell for just under newly manufactured cartriges.
Fired 49 - 56 Yugo and 74 - 76 czech, never had a misfire on 400 rounds. Quite dirty through.
