Even though IMR 4831 and H4831SC are unique powders, you can find that in several circumstances, in which one of these is outlined the other might be too. Also, you'll find there is a reasonably steady marriage amongst them with regard to listed loads.
I've used H4831 (and H4831SC), and I utilize it. There aren't many cartridges which i use it for as I appear to be often to gravitate to other powders. Having said that, I can not say that it won't operate. It is simply that Various other powders get the job done far better for a presented cartridge. For example, during the 280, H4831 gave me very good velocity and really fine groups with Nosler a hundred and forty AB. Nevertheless, RL19 was marginally superior in accuracy, even though the velocity was pretty much equivalent.
The obvious induce is really a rough/ruff bore. No number of copper fouling minimizing agents within the powder will probably right this.
Indeed you'll be able to. They're the exact same actual powder however the SC powder is simply Minimize shorter so it meters far better.
Anyway, I knew the two pounds of H4831SC utilized exactly the same data, but I did not know no matter whether there was nearly anything diverse among a pound of powder labeled "Excessive" and just one not so labeled. A simply call to Hodgdon verified they have been in reality similar and the sole big difference was the logo over the label.
Because there won't appear to be any "official" Load Data around for this Load, can many of you offer a starting point with this mixture and points to consider when Performing this Load up?
Nampa, Idaho In my experience the one actual distinction would be that the shortcut meters far better through reloading machines. The moment It truly is loaded theres no h4831sc load data purposeful big difference. I have heard which the shortcut might have a small little bit more rapidly burn fee but It appears insignificant.
and you might like to put money into some new load data books. powder composition and chemistry can does adjust over time. 4831 powder of years back isn't identical as precisely what is now available. that may be why an individual serious about reloading securely could have quite possibly the most existing load data textbooks to seek advice from.
Together with the short Slash Edition powder will come around The bottom in the reduce shoulder so I however have plenty of place.
You could have to produce a number of far more posts to h4831sc receive cleared to complete PM's. As you reach that position I would put up from the classified reloading segment to find out if any person is in your area to get a trade. Click h4831sc to expand...
Regardless of the similarity in nomenclature, they're absolutely various powders, with IMR 4831 staying considerably quicker compared to the Hodgdon variants. You should not deal with them as a similar powder, since they most absolutely will not be.
I use 52 grs H4831sc which has a 117gr Hornady BTSP. It is really accurate, gentle mannered, and knocks whitetails down DRT. If it was me, I would start out at fifty two gr and operate up.
I'm sure the H4831SC provides a much better load density But I think I've plenty of place in my case for the conventional H4831.
This seems like a superb place to divulge a little bit more information on Hodgdon, H4831 especially...I at the time experienced a pound of H4831SC sit on the shelf for a variety of yrs. It was ordered prior to Hodgdon began publicizing the "Extraordinary" line of powders, of which the H4831s are a part.
