Re: Retumbo loads for 300 Win Mag.
I use Retumbo in my 300 WM and get excellent results. My load is 79gr of Retumbo, Fed215, 210 Berger Hunting VLD's, .010" off the lands , Norma brass. I get 2902FPS and ES of 8FPS out of my 26" barrel. I have gotten good accuracy with the Berger 185's using 82 gr of Retumbo but did not measure the velocity. I would expect it to be 3050-3100. I would start a couple of grains lower and work up.
