This is often imagined to be the "head over to" powder-or darn near to it- for almost any bottle-necked cartridge a person could handload. It's the inspiration for countless pet loads, nonetheless I have not been pleased with the final results.
They may be the same matter, but H4831 sc is Lower shorter so it's going to pack right into a situation much easier then the traditional, and in some instances like our 7mm rem mag it makes it possible for us to add much more powder then just the normal H4831.
4gr of H4831sc and Federal 215 primers. I found this combo provides .5MOA teams with velocity about 3020fps away from a 26" barrel. I use this exact powder in my 300wm capturing 180gr tablets, so it's good to obtain just one powder for the two.
Run your load up with the specific powder (sc or standard) and whole lot you will be making use of although. Very same burn up rate does not imply it can behave "just" the identical. I have witnessed around one hundred fps difference between sc and mil-surp numerous H4831.
The only real variance as I comprehend it is that the SC was designed to perform by way of powder measures superior (which it does). The extended grains will not feed properly in the least in a few steps. Thats my 02 :grin:
I've made h4831sc load data use of H4831 and H4831SC in my 260 Rem with no distinction. The only thing will be the quick Minimize will give you somewhat more Place. Great luck!gun)
I don't love to work up a load working with one wide range of powder and after that have to operate up once more mainly because I run out and have to start out h4831 vs h4831sc employing a new great deal variety.
Anyhow, I wished to give some 7828SC a try and lessen several of the compression. What a miscalculation, I could not get this powder to shoot accurately or deliver the velocities I get with conventional 7828.
With h4831sc load data the quick Slice Variation powder will come as much as the base on the decreased shoulder so I still have plenty of area.
locutus reported: I however have a fantastic stockpile of H450, the ball powder equivalent of 4831, which flows via my powder steps efficiently.
Run your load up with the particular powder (sc or common) and lot you might be employing while. Same burn price doesn't suggest it is going to behave "particularly" a similar. I have seen more than 100 fps difference between sc and mil-surp plenty of H4831.
Just after looking through this short article (and a lot of Other individuals, but this a single is easily the most data driven with many accredited shooters) I've stopped worrying about touching or remaining in a magical distance from your lands, and started loading exactly where I could improve various areas of a load. Just my .02, ideally you may get one thing to work for ya.
A lot of the outdated Lyman data just listed IMR 4831, which was surplus navy powder and now more recent mfg as H4831.
If I've a pound or two of the powder and get much more of the same, only another ton amount, I will blend them all up so that I've a homogeneous batch of powder with which to work.
