300wm H1000 loads

Who has some good H1000 loads using 160-170g bullets?

IMO there aren't any! h1000 is slow burning and made for heavier 300 WM. You can about fill the case with 85 grains of H1000 and push in a 168 grain bullet and only create maybe 52000 psi and get it going 3100 fps.

H1000 will only shine in the 180 grain and above

What do you suggest??
I like to stick with IMR or H powders

For a 168 gr bullet, it's showing H1000 as the 2nd fastest. Hybrid 100V being the fastest but I am really not familar with that powder and if it is or isn't temp stable like H1000, H4350, Varget (seems like Hybrid 100V is NOT).

I'd probably mess around with H4350 in that weight class of bullets.

IMR 7977 with mag primer or 7828 using only large rifle primers

H4350 would be a better choice for 168's, H1000 is perfect for 180's on up.

Cheers.

If 4350 works, you could try RL16 for greater temp stability. If you can find it.

There is no way ANY powder is more temp stable than H4350…

I'm running rl26. I'm pushing 165g bullets right at 3200fps in my wife's tikka.

H4831sc for your 170 would be my recommendation

What bullets, i.e., Berger, Hornady, etc.? I have three 300 WMs, all shooting better with >180. If you have not seen it, do a search; BROZ has a thread with overwhelming success with Berger 210/215 and an H1000 load.

I'm using RamShot Hunter when RL-26 is not around. 77.9 grs with Barnes 168 gr TTSX bullets.
Very fast, very accurate in both of my Brownings.

Using the 180 gr "spbt" with 79.5 gr, H1000. LRM primers.

See pictures.
These are from a reduced 50 yd small bore for shooting @50'. Shot at 100 yds!
