This is imagined to be the "go to" powder-or darn close to it- for nearly any bottle-necked cartridge just one could handload. It really is the foundation for a lot of pet loads, yet I have never been pleased with the results.
They've executed identically for me. Like everyone else I rushed to find the newer SC Model but have now switched back. Preferably you wish about one hundred% loading density. In case you have sufficient scenario potential for that H4831(extended) you're probably much better off.
WARNING: This item can expose you to Lead, which is known into the Point out of California to induce most cancers and beginning defects or other reproductive harm. For more information drop by – .
Operate your load up with the particular powder (sc or common) and great deal that you are employing though. Very same melt away charge does not imply it is going to behave "exactly" precisely the same. I have seen in excess of a hundred fps distinction between sc and mil-surp plenty of H4831.
The one variance as I know it would be that the SC was built to get the job done by means of powder measures much better (which it does). The lengthier grains don't feed well at all in certain actions. h4831sc Thats my 02 :grin:
It can be probably that no further more discussion is needed, during which circumstance we suggest setting up a fresh thread. If however you are feeling your reaction is required you may continue to achieve this.
Hodgdon H4831SC (Quick Minimize) extruded rifle propellant is often a major option for massive recreation hunters who use handloader rifles. h4831sc load data Launched inside the nineteen fifties, this propellant is improved with shorter grain measurements which makes it possible for greater powder circulation and a lot more uniformity.
In truth, It really is even a smart idea to back down and operate up safely if you go from just one great deal to a different lot of the same powder.
WA I'd personally recommend a slower burner which will give far h4831sc load data better situation density like H1000 or IMR 7977, particularly if you are loading heavies prolonged.
You might have to create several far more posts to receive cleared to carry out PM's. As you reach that position I would article from the labeled reloading segment to determine if anybody is near you for a trade. Simply click to extend...
Regardless of the similarity in nomenclature, they're wholly diverse powders, with IMR 4831 becoming significantly more rapidly compared to the Hodgdon variants. Really don't handle them as the identical powder, since they most definitely are usually not.
That is an Intense extruded propellant and features heightened insensitivity to hot and cold temperatures.
Some of the aged Lyman data just stated IMR 4831, which was surplus navy powder and now newer mfg as H4831.
This looks like a good spot to disclose a little more details on Hodgdon, H4831 specifically...I after had a pound of H4831SC sit about the shelf for quite a few a long time. It absolutely was purchased before Hodgdon began publicizing the "Serious" line of powders, of which the H4831s are an element.
