I'm a real enthusiast with the H4831 powder. I get terrific velocity and accuracy out of any caliber I have tried it in. From the twenty five-06 up to your 338 it is actually my head to powder of option. I try every kind of powders when Operating up loads, however the H4831 constantly seems to appear out on top rated for precision and velocity when the situation is from the 06 class or greater.
Ballistically, Hodgdon H4831 SC Powder is the exact copy of H4831. Physically, it's a shorter grain size, as a result, the designation SC or brief cut. The shorter, additional compact kernels allow the powder to move in the powder steps more effortlessly, helping to relieve the regular cutting of granules.
The truth that the H4831 is in truth a slower burning powder is exactly why you happen to be viewing higher velocities acquired with that powder, in contrast to Anything you've witnessed Using the IMR things. Also fantastic powder, but somewhat superior suited to slightly smaller sized situations by using a little bit significantly less potential.
Operate your load up with the specific powder (sc or normal) and good deal you might be utilizing though. Exact burn charge doesn't suggest it is going to behave "precisely" exactly the same. I have witnessed in excess of 100 fps difference between sc and mil-surp lots of H4831.
My practical experience would be that the SC and SSC loaded to the identical fat given that the extended cut displays a decreased velocity.
Considering the fact that there won't seem like any "official" Load Data in existence for this Load, can several of you supply a starting point with this mix and items to consider when Functioning this Load up?
Nampa, Idaho In my encounter the only real real difference is that the shortcut meters far better by way of reloading products. As soon as It truly is loaded theres no functional difference. I've listened to that the shortcut could have a tiny little bit more quickly burn fee but it seems insignificant.
Actually, It is even a good idea to back down and work up safely when you go from one lot to a different lot of exactly the same powder.
I could stack em in a single gap but I wasn’t content with the velocity. Immediately h4831sc load data after months, I bought Blessed and caught some H1000 on the net and naturally paid out a bit extra. The quite subsequent 7 days at a gun show a man had an entire scenario of H1000 for $40 per 1lb. I fail to remember simply how much, but h4831sc load data Together with the H1000 I’m now pushing a 160gr about 3200 and it’s a gentle load.

Regardless of the similarity in nomenclature, They are absolutely different powders, with IMR 4831 getting considerably a lot quicker compared to the Hodgdon variants. Do not deal with them as precisely the same powder, because they most undoubtedly are certainly not.
Like Anyone stated, the SC stands for “brief Reduce” and is particularly a little bit easier to meter. Would make you issue why they would continue to make the frequent just one.
A number of the old Lyman data just stated IMR 4831, which was surplus navy powder and now newer mfg as H4831.
I could stack em in a single hole but I wasn’t content with the velocity. Immediately after months, I obtained Fortunate and caught some H1000 on the web not to mention paid out somewhat further. The really up coming week in a gun clearly show a guy experienced a complete situation of H1000 for $forty per 1lb. I forget about simply how much, but with the h4831 vs h4831sc H1000 I’m now pushing a 160gr about 3200 and it’s a delicate load.
