My 300 Win Mag seems to shoot best at well under max loads. For example I can get the 220 Sierra Matchking going 2900 fps safely but accuracy is best at 2815 with H1000. Also I can get the Nosler 200 Partition going 3000 fps safely but accuracy is best at 2850. The Swift 180 Scirocco is shooting best with 75 grains of RL22 but I can safely load 77 grains. I wonder if this is normal? I had generally heard and experienced with other rifles that my most accurate loads tended to come at the max powder charges. I also wonder if switching to a different powder would enable me possibly to get equally good accuracy at a higher velocity. I have heard that there are accuracy nodes that come at different velocities. Perhaps I have not been able to find the next faster node with the powders I am trying. I know that it will not make much difference to the animal whether it is hit with a bullet going 2600 or 2800 fps on impact but a higher muzzle velocity would flatten trajectory and reduce wind drift a bit. Additionally it goes against the grain to have a downloaded 300 Win Mag. Would be nice to have it loaded to its potential. Any thoughts? Thanks, Rufous.
