Though IMR 4831 and H4831SC are various powders, you'll discover that in lots of occasions, wherever one of them is shown the opposite will likely be also. Also, you'll find there is a reasonably regular marriage involving them with regard to detailed loads.
They have got executed identically for me. Like Absolutely everyone else I rushed to get the more recent SC version but have now switched back again. Preferably you desire about 100% loading density. When you've got adequate circumstance capability for that H4831(extended) you will be almost certainly improved off.
The truth that the H4831 is in fact a slower burning powder is exactly why you are seeing greater velocities received with that powder, versus Everything you've noticed Using the IMR things. Also very good powder, but fairly superior suited to slightly more compact situations using a little bit considerably less capacity.
I've had a number of rifles that fouled genuinely lousy. Acquiring every one of the copper out was a true PIA till I discovered Wipe-Out foaming bore cleaner.
Thornton, CO Supply of H4831SC is starting to dwindle down way too so get what you would like for the new load I'd counsel. Could be all of very little if they restock every thing shortly but People powders are owning transportation regulation issues.
I've used H4831 and H4831SC in my 260 Rem without change. The only thing would be the shorter Reduce provides a bit more space. Good luck!gun)
I am applying it having a 210 Berger. In my rifle, H1000 wasn't as precise. RL22 did properly but I had been a bit concerned about temp security. I believe I'm at 72 grains h4831sc load data and get all-around 2850ish fps
Like stated above, similar stuff. h4831sc load data All of that differs is the dimensions from the kernels. I did hear someplace that they are going to only make the SC Sooner or later. I do not know if that is accurate or not but would sound right to me. I take advantage of SC since that is definitely what I present in the 8 lb jug and it works.
I've found the precise opposite to get true in my gun. H4831SC was the slowest powder with one hundred eighty g Accubonds. RL22 was a much faster and Similarly correct powder in my three hundred Gain Mag.
Ballistically, this Extreme Extruded powder is the exact duplicate of H4831. Bodily, it's a shorter grain size, hence, the designation SC or short Reduce. The shorter, far more compact kernels enable the powder to move with the powder measures additional effortlessly, assisting to ease the consistent slicing of granules.
Despite the similarity in nomenclature, they're completely diverse powders, with IMR 4831 remaining considerably a lot quicker compared to Hodgdon variants. You should not treat them as the exact same powder, because they most undoubtedly will not be.
This is often an Intense extruded propellant and delivers heightened insensitivity to cold and hot temperatures.
Some of the aged Lyman data just mentioned IMR 4831, which was surplus armed forces powder and now more recent mfg as H4831.
The container did not h4831sc load data possess the "Intense" brand on it. A coworker And that i then swapped some powder, And that i ended up with A further pound of H4831SC, this just one While using the "Serious" brand on it.
