I just recently purchased a .338 Lapua Magnum 700 P MLR and reloaded all kinds of different recipes for the 250 and 300 smk. My first shot was wayyyy below max for the 250 and the overpressure was intense! I put those away and proceeded to start with another load. Again overpressure....(slightly sticky bolt, EJECTOR marks although no split necks or separation of anykind on the casing it's self. Well I decided to do an oal test and found that my throat is SHORT. About 3.495 to 3.525 to be an estimated guess. My question is how do I go about reloading meaning do I load them shy of my lands and decrease powder charge or do I increase powder charge? I have never experienced anything like this. I believe the minimum oal is somewhere around 3.6??.. but anyways I would love to hear some opinions as to what and how to solve this problem and still achieve velocity and accuracy. Thanks, aimsmall
