190 Bergers, 300WM

[7mmSendaro]

Anyone have a good load using 190 grain Berger VLDs in a 300 WM? I plan to try some in my rifle if I can ever get them!

Thanks

Thanks for the info. What velocity did you get from this load? What barrel length do you have?

26" barrel average velocity 3025fps my average group size is 1/2"-3/4"

7mmSendaro,
I tried some back in February in my Savage 112BVSS with RL25 and didn't get great results. I am going to re-visit the 190's with RL22, IMR7828 and possibly a few faster powders. I was also using WLRM primers that day and temp was 40deg.
I tried from 75.0gn to 77.5 in 1/2gn increments:
75.0 - 2932fps @ 1.1705"
75.5 - 2971fps @ .893"
76.0 - 2991fps @ 1.342"
76.5 - 3021fps @ .510"
77.0 - 3070fps @ 1.2135"
77.5 - 3073fps @ 2.011"

I tried 76.5gn again, both with WLRM and R9.5M primers and velocity was pretty much the same (W:3053fps, R:3012fps) but accuracy was 2.441" for WLRM and 1.051" for R9.5M primers.
I know your rifle will be totally different for velocity and accuracy, but it gives you somewhat of a range as to what you should expect. Hope this helps. JohnnyK.

Which powder were these results from?
