IMR 4064 and .300 WSM
I'm looking for some load information for a 180gr bullet in .300 WSM using IMR 4064, but I'm drawing a blank. The old IMR site I found doesn't list the WSM and the current Hodgdon site to which I was transferred doesn't list IMR 4064.
Does anyone have any ideas? |

Not in Lyman, either.
4064 is fast burning for such a large case, probably why they didn't bother with it. |

Yep too fast.
Here's a few suggestions if you want: Ramshot HUNTER VihtaVuori N560 Either one will get you 3000 fps @ 24" |

I use IMR 4064 in my .375 H&H. Works great.

IMR4064 is a good powder in the 308 Win. Its really pretty fast for the 300WSM

4064 in 300 WM
Lyman 44th Edition, 180 grain jacketed bullet;
starting load, 56.0, v= 2590 max 62.5, v= 2840 All testing done with Winchester 120 primers. This was published in the late 1960's so the 4064 of today may not be the 4064 of your father. |

Even if you find data for 4064 it won't give you good results in 300 WSM.
I got best accuracy with H4350 in my 300 WSM. RL17 is supposed to be a good choice too. But if you try RL17 do it with a chronograph and caution. They show max loads considerably faster than other powders. In some rifles it works fine. In mine I reached a point where I was getting speeds exceeding what was expected 2-3 gr below book max with over pressure signs.
