300wm H1000 loads

What Powders do you have, that you can use, or are you just curious about H1000.
I have been playing with a 300WM of some kind over 40yrs.
Just trying to help.

I have on hand right now, Imr and H 4350 and H1000

I would definitely go with the H 1000. I have tried both IMR and H 4350 in my 6.5x284 norma and the H 4350 is by far more stable than the IMR.

Go ahead and try H-1000, if you don't like it, H-4350 is the easy button.
Let us know how you do.

That has not been my experience shooting both through 30-06 in S. TX heat.

Well, I worked at the plant (ADI) where it's made and the test was performed from -20°C to 50°C and the result was 10fps difference total from those temperature extremes. This was a military temperature test to guarantee that ADI ammo was suitable for desert use.
The full range of Extreme powders performed very similarly and are the most temp stable powders made.

Cheers.
