That is purported to be the "drop by" powder-or darn near to it- for almost any bottle-necked cartridge just one could handload. It's the inspiration for countless pet loads, but I have not been pleased with the final results.
They have performed identically for me. Like All people else I rushed to obtain the more recent SC Variation but have now switched back again. Ideally you wish about one hundred% loading density. Should you have enough scenario capacity to the H4831(extensive) you will be in all probability greater off.
The truth that the H4831 is indeed a slower burning powder is specifically why you happen to be observing increased velocities acquired with that powder, as opposed to Anything you've witnessed Using the IMR things. Also good powder, but rather far better suited to slightly scaled-down circumstances with a bit a lot less capacity.
Minnesota H4831SC is my head to from the 7mm Rem Mag, but I am saving the tiny I've left for drop 2021. I would get started reduced and perform your way up, determined by what load data you look at for this combo the min/max loads are everywhere in the board.
INgunner54 stated: It has been a little bit, but I did get some 4831 SC to try. Observed a node and shot some groups.
Since there won't appear to be any "Formal" Load Data out there for this Load, can some of you present a starting point with this mixture and things to think about when Doing the job this Load up?
Everyone loading 7mm Rem Mag with H4831sc? How are the outcome, any data you may share? Also needs to mention I've some ELD-X one hundred seventy five's I want to check out, if you have facts on that likewise.
excaliber explained: I've uncovered the precise opposite being true in my gun. H4831SC was the slowest powder with one hundred eighty g Accubonds. RL22 was a considerably quicker and equally accurate powder in my three hundred Earn Mag.

This is often an Intense extruded propellant and gives heightened insensitivity to cold and hot temperatures.
Even though IMR 4831 and H4831SC are unique powders, you will find that in many circumstances, wherever one of these is listed the other will h4831 vs h4831sc likely be at the same time. Also, you will discover there is a reasonably dependable relationship in between them in regards to detailed loads.
Certainly, sitting all over for h4831sc load data twenty+ a long time (I'm sure a guy who remains to be utilizing the H4831 he bought while in the 60s), means that burn up premiums will probably modify a smidge, and new manufacture things will likely be somewhat unique too.
