Although IMR 4831 and H4831SC are diverse powders, you will see that in several occasions, where one of these is detailed the opposite will probably be likewise. Also, you will discover there is a fairly constant romance in between them with regard to shown loads.
I have applied H4831 (and H4831SC), and I utilize it. There aren't lots of cartridges that I utilize it for as I seem to be constantly to gravitate to other powders. However, I am unable to express that it does not do the job. It is just that some other powders function better for your offered cartridge. For instance, during the 280, H4831 gave me very good velocity and really fantastic teams with Nosler 140 AB. On the other hand, RL19 was marginally superior in precision, while the velocity was virtually similar.

Together with the 154 grain Hornady SP while in the 280, H4831 gave me superior groups and very good velocity, but Rottweil R905 contains a significantly greater velocity and gives marginally far better precision. With Swift one hundred fifty grain Sciroccos from the 7mm RM, H4831SC gave great accuracy and velocity, but RL22 was marginally greater. Consequently, in Just about every of these cases I went with another powder, but I would definitely dislike to divest myself of the H4831.
The only big difference as I know it is that the SC was meant to operate via powder actions greater (which it does). The for a longer period grains usually do not feed perfectly at all in some steps. Thats my 02 :grin:
It can be possible that no further dialogue is necessary, wherein circumstance we propose starting off a whole new thread. If even so you are feeling your response is necessary you may even now do so.
Nampa, Idaho In my working experience the only real real distinction is that the shortcut meters far better by way of reloading devices. At the time It truly is loaded theres no useful variation. I have listened to that the shortcut could have a small bit quicker burn price but It appears insignificant.
Like mentioned earlier mentioned, similar things. All of that is h4831sc different is the dimensions from the kernels. I did hear somewhere that they're going to only make the SC Down the road. I don't know if that is genuine or not but would seem sensible to me. I exploit SC mainly because that may be what I located in the eight lb jug and it works.
I have found the exact opposite being true in my gun. H4831SC was the slowest powder with 180 g Accubonds. RL22 was a considerably faster and equally exact powder in my three hundred Gain Mag.
What's more, it goes on to say that due to fshorter grains, that load density might be somewhat increased.
Operate h4831sc load data your load up with the precise powder (sc or common) and ton you might be employing however. Exact burn off fee doesn't suggest it will behave "particularly" exactly the same. I have viewed about h4831sc load data one hundred fps distinction between sc and mil-surp lots of H4831.
Again to old web site Near When there is anything within your cart, it will not be brought about into the old web site.
Southwest Idaho I attempted H4831sc in my 300 WM but experienced much better pace and accuracy with H1000. I might relatively utilize a slower burning powder with 215g products.
This looks like a great location to divulge a bit more facts on Hodgdon, H4831 especially...I the moment experienced a pound of H4831SC sit on the shelf for a number of decades. It was ordered just before Hodgdon commenced publicizing the "Intense" line of powders, of which the H4831s are a part.
