Well now i've got my wyatt mag box installed i'm going to try out my new hornady OAL tool but I know while seated closer to the lands pressure will spike . What is your sweet load for your 300 RUM . my old load was seated just shy of the factory mag box 85.5 grains of Retumbo & 215M primer nosler custom brass. Iwant to do like most on this site are doing i want to pack all the powder I can get away with and achieve maximum accuracey/safety/ and MV .
Thanks in advance your help .
