However IMR 4831 and H4831SC are different powders, you will find that in several instances, where by one of these is mentioned the opposite might be at the same time. Also, you will find there is a fairly constant romance in between them with reference to stated loads.
I have applied H4831 (and H4831SC), and I utilize it. There usually are not lots of cartridges which i utilize it for as I seem to be constantly to gravitate to other powders. Having said that, I am unable to declare that it would not do the job. It is simply that some other powders work better for just a supplied cartridge. By way of example, while in the 280, H4831 gave me superior velocity and really fantastic groups with Nosler a hundred and forty AB. Even so, RL19 was marginally far better in accuracy, although the velocity was virtually equivalent.
That you are suitable They are really a similar the SC is brief Minimize so it meters greater, I do not Assume you may get just typical 4831 anymore
Indeed you can. These are exactly the same specific powder however the SC powder is simply cut shorter so it meters improved.
IMR powders also preform very well for me with one noteworthy exception. The many chrongraphing I have carried out with them indicates the velecity is consistant higher than 32 levels but starts to change once the temp begins to drop. The nearer to zero I get the greater they differ. I have noticed approximately 250 fps in a ten shot string with my 243 and 223 within the winter time close to listed here. Have not witnessed this with several of the other powders.
Considering that there would not appear to be any "Formal" Load Data to choose from for this Load, can many of you offer a starting point with this combination and items to consider when Performing this Load up?
Nampa, Idaho In my expertise the sole actual variation would be that the shortcut meters greater through reloading equipment. As soon as It is loaded theres no functional difference. I have read the shortcut could have a small bit faster melt away charge but it seems insignificant.
The SC or SSC designated powders Usually permit for increased load density, so that you can usually get a bit extra powder inside of a supplied situation when utilizing compressed loads. Usage of a fall tube can additional increase this advantage.
WA I might advise a slower burner that will give superior scenario density like H1000 or IMR 7977, particularly when you are loading heavies long.
Ballistically, this Extreme Extruded powder is the exact duplicate of H4831. Bodily, it's a shorter grain sizing, hence, the designation SC or limited Slash. The shorter, extra compact kernels enable the powder to movement from the powder h4831 vs h4831sc steps more efficiently, assisting to ease the constant reducing of granules.
Despite the similarity in nomenclature, They are fully diverse powders, with IMR 4831 getting substantially faster than the Hodgdon variants. You should not take care of them as the identical powder, as they most unquestionably are certainly not.
The "SC" stands for Limited Cut. I have not noticed a difference between possibly powder dut I don't Consider I would combine them.
A number of the outdated Lyman data just listed h4831 vs h4831sc IMR 4831, which was surplus navy powder and now more recent mfg as H4831.
The truth that the H4831 is in truth a slower burning powder is specifically why you might be seeing greater h4831 vs h4831sc velocities acquired with that powder, in contrast to Anything you've seen Using the IMR stuff.
