I am trying to find some data for h4831 in my 6.5 creedmoor. I was able to get a ton of h4831 for a stupid low price so I want to stick with it. Hoping I can get it to work with 130gr to get a little more speed. Anyone have any data for this? Thanks!
6.5 creed with 130gr ELD-M and h4831

Start with a 130/H4350 data max charge and work up. My guess is you end up in the 46-48 gr range if you can fit it in the case.

I ran up to 46.0 grains in new Lapua brass with the147eldm obviously with a longer COAL than SAAMI.
At 46gr It topped out at 2732fps from a 23" barrel and there was no signs of any kind of pressure.

^^^^ a safe bet.
you’ll probably run out of room before you find big speed or pressure But accuracy and ES should be excellent
Well just got all the components and loaded up some test rounds. Going to do a Ladder test starting at 41g h4831. Ended up running out of room at 46.5g with Nosler large primer. Depending on how it turns out I may try with hornady LP or starline SP see if I get any difference. Hoping to shoot later this week.
Note: using 130g ELD-M with COAL: 2.777”

It’s an AR-10 and I’m running Hex mag and the internal length is 2.800 (maybe a couple thou smaller not home to remeasure) I wanted to give my self enough room to feed well.
That powder is probably too slow for 130 gr in a gas gun.
You will end up with low velocity and high port pressure and probably a dirty burn.
If the accuracy is good just adjust your gas block and roll with it.
