    Just getting started with this caliber. I am primarily interested in loading the 300MK.
    Would anyone care to offer some of their favorite loads?
    I have Lapua cases and a 32" Broughton 5C barrel.

    I'm on the same boat but, here's what I gathered so far. For 300 grain SMK... 94 grain of H-1000. Went out this morning fireforming brass using 250 SMK and 94 grain of H-1000. Here's 2-3 shot group at 100 yards.
