H4831SC can be an Extraordinary extruded powder and the precise ballistic copy of H4831. Bodily, it's a shorter grain measurement which acquired it the 'SC' designation for 'shorter cut.' The shorter, more compact kernels enable the powder to circulation throughout the powder steps more effortlessly, helping to reduce the frequent cutting of granules. While using the smoother stream properties arrives a lot more uniform charge weights, when the person grains orient additional compactly, making much better loading density.
That means the knowledgable handloader can, with some extrapolation, discover a starting off load when just one is listed for a specific cartridge.
I picked up the Hodgdon yearly reloading info magazine yesterday and they say h4831 and h4831sc hold the exact same burn prices. Advantage to h4831sc is best metering and having the ability to get a lot more uniform load density with shorter kernels In accordance with them. Info is similar for equally.
INgunner54 explained: It has been a little bit, but I did get some 4831 SC to try. Found a node and shot some teams.
Kansas Town, MO I'd grab whatsoever is accessible today. I’ve utilized both of those nevertheless with my head over to load and didn’t see anything distinctive efficiency intelligent.
I'd personally hope that should they were to take a 50,000 pound large amount of powder and leave fifty percent as extended cut and another fifty percent as SC that nobody could convey to the difference.
no tension signs in any way. I was not considering overloaded, just possibly would recuperate grouping if I slowed it down some. I don't need to slow down a lot of while, I'd like for my hunting load to stay about 3000 fps. Seems like I have an justification to but a chronograph. Click to broaden...
IF they are saying that 1 powder is equivalent to a different, then it's the same Vitality density and melt away price inside + or - 5%. To put it differently, IF they are saying that H4831 and h4831 powder H4831SC are interchangeable, then the variation between H4831 and H4831SC will probably be no worse than good deal A of H4831 and good deal B of H4831.
Stick with H4331 or H4831SC as it has been mentioned IMR is just a bit more rapidly and more than a tad higher in its strain curve. In which are you presently locating your load details? Here's an posting That may be of fascination to you. Very good luck , Cheers

This looks like a superb location to disclose somewhat more data on Hodgdon, H4831 exclusively...I after experienced a pound of H4831SC sit to the shelf for many many years. It was obtained right before Hodgdon commenced publicizing the "Excessive" line of powders, of which the H4831s are a part.
They even once informed a benchrest shooter that if he provided them adequate 8208 that they could duplicate it for him, but he would have to foot the Monthly bill for most or all the lot. They took his powder, and his money.
The obvious trigger is often a rough/ruff bore. No number of copper fouling decreasing brokers within the powder will probably correct this.
Chugiak, AK I often hear about this temperature sensitivity thing. Can it be genuinely that significant of a difficulty? I have in no way regarded as it to be a dilemma Except I am sighting/capturing in 80+ diploma weather conditions and around max loads.
