Need some input here. I'm currently shooting a custom 300 RUM, with a 28" 10 twist match barrel. This is not a bench gun, its a long range hunting gun. I'm pushing a 178 gr A-Max with 98 gr of Retumbo at 3500 fps and getting .336" at 100 yards with five shots. I'm thinking of trying a 110 gr V-Max with the suggested H-4831. What are your thoughts, and has anybody loaded this? This would be a GHog load if it will work. Your suggestions please.
