So my new play toy should be ready in a couple of weeks. Im having a gunwerks 7mm Lrm built but do to the current powder situation I cant find any Retumbo for my baby. My question is does anybody have any load data for the 7LRM using the new 178gr Nosler LR Accubonds using H-1000? My gunsmith is using 72 grains of Retumbo getting 3050fps, he told me to start with 70grains of H1000 and start from there. Does this sound close to about rite? He switched from H1000 because he was getting pressure without velocity with 180gr bergers and never loaded the Noslers over h1000. I just dont want to blow up a $3500 gun with the first shot. I have contacted Mike at gunwerks about this and he said they havent done any load data yet with them.
