I recently installed my Remington .338 Lapua into a AI 1.5 chassis and noticed my Remington gold medal match 250 grain ammo will not fit in the magazine? What is the correct OAL should I use so they fit and feed in the standard magazine? Thanks.
91.5mm max is what I load mine to. Off the top of my head I'm not sure what factory ammo will fit apart from (and I'm just guessing) Lapua 250 Lock Base factory.
