I've starting reloading some 30-06 loads for my Steyr Prohunter, and picked up a whole selection of bullets, the triple X shocks looking pretty interesting. With the reduced friction due to the grooves, and subsquent lower pressures produced, has anyone 'overloaded' their loads by the 2 grn. max stipulated by Barnes? They say to advance the loads in 0.5 grn. increments. Higher velocities are always desired, but do these long bullets stay pretty stable?
