Re: 300 WM load recipes for bergers

Retumbo will be best suited for the heavier 200 plus grain bullets. It's a slow burner. I use 75.3 grains of Retumbo with slight compression in my 230 grain loads to drive them at around 2800 fps. I'd guess somewhere around 77-78 grains for 200-210s. It'll work, but expect to crunch it a little.

    Re: 300 WM load recipes for bergers

    GOD, so many strange words and numbers being used to describe powders on this forum these days.. I thought the only powder made was H-4350 !!! Guess you know my choice again... Could it be that if you only had one powder to used from 25/06 to .338 super mags that you could find a better choice than H-4350!! Accurate, Clean, Reasonable velocities with every bullet weight, one powder for just about everything, I used to try them all also, and finally determined why go through this all time... H-4350, about as good as it can get in anything I ever found..

    Re: 300 WM load recipes for bergers

    I just worked up a load yesterday with the 215 Berger Hybrids in my 300 win. Load work up was easiest I have seen. 3 shots to find max pressure, then first 3 shot group went .190" and the velocity was steller across my Oehler 35.

    I still need to test these for terminal performance on game but the ballistics part is pretty impressive when you take a 215 gr bullet with a G1 BC of .696 and a MV over 3000.

    COAL is 3.633", they fit in the mag box and feed, as well as extract loaded.

    H-1000 is the powder for me in a 300 win. Velocity at 1000 yards is still 1973 fps. with 1859 ft lbs of energy and it only takes 20.5 moa from a 100 yards zero to get there.

    Sorry bud, not sure on charge weight. Some sources show a 200 grain pill; simply use a 180 or 185 instead of the 200. I'd look at using 200-220 grain bullets with retumbo for full throttle stuff though.
