H1000 or H4831sc 300WM and 180s?

[Herschel34]

Which powder, H1000 or H4831sc, do you think will give me the best accuracy in my 300WM with 180 nosler ballistic tips?

Thanks!!!

What barrel length, twist, and rifling?

24", 1-10, 5r

I don't have a 300 WM, but I do have a 300Winnie necked down to 7mm and I use H1000 (74g) and Retumbo w/ 7mm 180 Bergers to get to 3050fps. H4831 didn't get me where I was going. I would think you'll have better luck w/ a slower powder than H4831. Good luck.

^^^^I just switched from H4831 to H1000 as well but in 7mm and picked up velocity as well

Thanks for the replies!

Anybody with any experience with the 300wm?

I run H4831 with 180 NBT and save the H1000 for the 215HVLD's.

I run 78.7gns of H1000 behind a 185 vldh and get 3035 fps from a 26" 1/10tw.

I run my 300 with 77.3 grs Hybrid 100V, 190 Mk's Rock Creek barrel 11 twist. Very accurate for me. IMR4350 is showing me promise as well as IMR7828SSC.
