H4831 for 300win mag?

[C. Thomas]

I bought a Christensen Mesa long range, 300 win mag, 26" barrel, 1:10 twist. Planning to load some Berger 210 VLD's, problem is I was wanting to use H-1000 but I cannot find any at local stores or online. I do have a few pounds of H4831, any problems with this powder and bullet combo? Or does anyone know where some H-1000 could be bought at? Thanks for the help.

Look at you manuals, according to mine H4831 or ADI AR2213sc is a suitable powder with 300WM up to 230gr projectiles so it should work just as well as any others would.
And probably the good thing about it is that even at that weight pill the loads are not compressed!

With H-1000 or ADI AR2217 you start getting into compressed loads at the upper end of the charge range.
Im not saying compressed loads are a bad thing generally but it can cause some seating issues at times.

I used H4831 in a .300 Win Mag with 208gr ELDs. The load was 73.0gr and it went around 2880fps. Not a super hot load, but it works well.

I have used H4831 SC with success, but not as good as H1000

H4831 will work fine, not optimal but plenty good. I know some hunters whose favorite load for their 300 WM is a load with H4831, esp with lighter bullets. In addition it is not esp. sens to temp variations. If you continue to be unable to locate any H1000, RL26 is another good alternative.

H1000 works better that h4831 on the heavies but h4831 works well with 175 grain bullets and smaller. Atleast this is my experience.

I have used H-4831 in my 300 Win mag with 180 gr bullets with good results. What I have found is with heaver bullets, like 200 gr+ slower powders are better. IMR-7828 has been good for me as well as some slower ones. RL-26 works good but very hard to find.

Had pretty good luck with h4831 but little slow. Rl 23, 25, 33 good powders


H1000 and rl 26 little tough to find. any slow burning powder around h1000 is worth a look at if u have on hand.
Cheers

I always allow myself 1 stupid question per day on this forum. I been using IMR 4831 in my 300 WM and thinking of switching to H4831 for the more temp. stability. Question is what does the SC stand for on H4831 SC and what are it's advantages?

S C stands for short cut. You can get more weight in your case than the standard H-4831. The grains are cut shorter than on the standard H-4831

Means Short Cut.
The original version was longer & wasn't really a friendly powder to stacking into a cartridge, so the longer granule was cut shorter to help this.

SC stands for short cut. You can fit more in a case really only advantage. H4831 and H4831 SC are interchangeable. IMR 4831 and H4831 are not. You should get a slight fps advantage from H4831 plus very temp stable
