Given that there does not look like any "official" Load Data to choose from for this Load, can a number of you offer a place to begin with this mixture and things to think about when Operating this Load up?
H4831SC Powder out there in stock now. Ballistically, this Excessive Extruded powder is the precise copy of H4831. Bodily, it has a shorter grain sizing, as a result, the designation SC or limited cut. The shorter, additional compact kernels allow the powder to circulation through the powder actions more effortlessly, helping to reduce the continuous slicing of granules.
The point that the H4831 is in fact a slower burning powder is specifically why you are seeing better velocities acquired with that powder, versus That which you've noticed With all the IMR things. Also very good powder, but relatively improved suited to marginally smaller cases that has a bit a lot less capacity.
While using the 154 grain Hornady SP within the 280, H4831 gave me superior teams and good velocity, but Rottweil R905 includes a appreciably bigger velocity and provides marginally much better accuracy. With Swift a hundred and fifty grain Sciroccos during the 7mm RM, H4831SC gave excellent accuracy and velocity, but RL22 was marginally much better. Consequently, in Each and every of those scenarios I went with another powder, but I will surely despise to divest myself of the H4831.
In any case, I knew The 2 lbs of H4831SC employed exactly the same data, but I didn't know regardless of whether there was something distinctive among a pound of powder labeled "Extreme" and one particular not so labeled. A contact to Hodgdon confirmed they were being in reality equivalent and the only variation was The brand within the label.
It truly is most likely that no further discussion is needed, by which circumstance we advocate beginning a completely new thread. If on the other hand you're feeling your reaction is required you'll be able to still do this.
I have utilized the two and made use of the exact same rates and have not been ready to inform any noticable dissimilarities with functionality. the SC version meters somewhat smoother is about all. any opinions??
excaliber explained: I've found the exact reverse for being legitimate in my gun. H4831SC was the slowest powder with 180 g Accubonds. RL22 was a considerably quicker and equally correct powder in my three hundred Win Mag.

What's more, it goes on to express that due to the fshorter grains, that load density may be slightly bigger.
This really is an more mature thread, you may not receive a reaction, and will be reviving an aged thread. Make sure you take into consideration creating a new thread.
Right after reading this text (and plenty of others, but this one particular is the most h4831 vs h4831sc data pushed with multiple accredited shooters) I've stopped stressing about touching or becoming in just a magical distance through the lands, and began loading in which I could improve numerous areas of a load. Just my .02, hopefully you may get one thing to operate for ya.
Though IMR 4831 h4831 vs h4831sc and H4831SC are various powders, you will discover that in lots of cases, in which one of these is mentioned another is going to be in addition. Also, you will find there is a fairly regular partnership involving them with regard to detailed loads.
This looks as if a good spot to disclose a little bit more info on Hodgdon, H4831 especially...I at the time experienced a pound of H4831SC sit around the shelf for quite a few decades. It absolutely was bought ahead of Hodgdon commenced publicizing the "Extraordinary" line of powders, of which the H4831s are an element.
