Though IMR 4831 and H4831SC are unique powders, you will see that in many cases, the place one of them is listed the opposite will likely be in addition. Also, you will find there is a reasonably regular romantic relationship involving them in regards to shown loads.
I've used H4831 (and H4831SC), and I use it. There are not lots of cartridges that I utilize it for as I appear always to gravitate to other powders. Having said that, I can not express that it will not do the job. It is just that Various other powders get the job done much better to get a offered cartridge. For instance, in the 280, H4831 gave me superior velocity and very high-quality groups with Nosler a hundred and forty AB. Nonetheless, RL19 was marginally better in accuracy, though the velocity was nearly identical.
It really is probable that no further discussion is needed, in which case we advise starting a completely new thread. If even so you're feeling your reaction is required it is possible to nevertheless do so.
Meaning the knowledgable handloader can, with a few extrapolation, look for a starting up load when only one is outlined for a specific cartridge.

Liberalism; The unachievable however acknowledged notion that it's solely attainable to choose up a h4831sc turd from the clean up conclusion.
Operate your load up with the specific powder (sc or frequent) and good deal you are employing even though. Exact burn up level doesn't mean it'll behave "particularly" exactly the same. I have seen above a hundred fps distinction between sc and mil-surp a lot h4831sc load data of H4831.

I realize the H4831SC provides a greater load density But I think I've more than enough home in my situation for the conventional H4831.
The reality that the H4831 is in truth a slower burning powder is specifically why you're seeing greater velocities acquired with that powder, rather than That which you've found with the IMR stuff.
