A little OT but its a little story. When my dad was travelling through Greece and Turkeyicon on the early seventies him a and a mate came across a some Greek soldiers on the border, They were armed with 1903 Sprinfields and Brens. Due to some mix up someone had forgotten to tell the soldiers that 30.06 ammo doesn't go in a bren gun! so they found some -303 and showed the soldiers how to load a bren mag and the diference between the two cartridges.
