I'm shooting a remmy 700p 300 mag with 190 gr HPBT's. I started working on my OAL. When I use the Hornady OAL gauge to measure how far out I have to seat my bullet to hit the lands, I get 4.133"( base to ogive) which puts the 190 matchking flush with the case neck. I obvioulsy cant seat my bullet to be close to the lands, right? How much of the bullet should I have in the case neck (some say if doesnt matter, and others have said I should have the neck of the case filled with the bullet)? should I switch to a heavier/longer bullet 220's?
