    Wondering if anyone has load data for these. I'm really curious if anyone is shooting the heavier bullets, 215 or 230 gr. Any idea on velocity???

    Thanks

    With RL17, I was able to get about 2930 fps shooting the 210 Bergers out of a 24 3/8the" barrel. One of our members swithched from the 210' to the 215's in his 300 WM and got about 50 fps more velocity from them. The 215's have a shorter bearing surface.

    RL17 gave me about 200 fps more velocity then other powders so subtract 200 fps from the above if you use another powder.
