This really is supposed to be the "head over to" powder-or darn close to it- for almost any bottle-necked cartridge 1 could handload. It is actually the muse for numerous pet loads, nonetheless I have not been content with the outcome.
On the subject of bench rest matches, Hodgdon® rifle powders have posted a lot more wins than all other propellants combined. A high-quality extruded powder, it flows correctly and effortlessly by means of actions and provides match-grade precision when put to utilize.
What is the primary difference? Compression. With no Extraordinary/major compression related to the lengthy grain 7828, the tension curve was altered and the load fell aside.
Minnesota H4831SC is my head to from the 7mm Rem Mag, but I am preserving the little I've remaining for tumble 2021. I might start reduced and operate your way up, determined by what load data you evaluate for this combo the min/max loads are all around the board.
The sole distinction as I understand it would be that the SC was built to operate as a result of powder actions far better (which it does). The lengthier grains do not feed perfectly in the least in a few measures. Thats my 02 :grin:
Due to the fact there doesn't appear to be any "official" Load Data in existence for this Load, can some of you supply a starting point with this mixture and factors to consider when Performing this h4831sc load data Load up?
Nampa, Idaho In my encounter the only real actual variation is that the shortcut meters better by means of reloading products. After It really is loaded theres no useful big difference. I've heard the shortcut could possibly have a tiny little bit quicker burn off price but it seems insignificant.
Anyhow, I desired to give some 7828SC a try and minimize many of the compression. What a oversight, I couldn't get this powder to shoot properly or deliver the velocities I get with standard 7828.
I could stack em in a single gap but I wasn’t satisfied with the velocity. Right after months, I obtained Blessed and caught some H1000 online and of course paid just a little more. The pretty next h4831sc load data week at a gun exhibit a man experienced a complete scenario of H1000 for $forty for each 1lb. I ignore how much, but Using the H1000 I’m now pushing a 160gr about 3200 and it’s a gentle load.
locutus stated: I even now have a very good stockpile of H450, the h4831sc load data ball powder equal of 4831, which flows via my powder steps smoothly.
I required somewhat additional myself so I went in advance and grabbed the 8lb jug to be coated for some time (and also have an abundance of the same large amount of powder).
Like Anyone mentioned, the SC means “brief Slice” and is a little bit much easier to meter. Tends to make you problem why they might nevertheless make the frequent 1.
rayporter said: i never observed a distinction apart from the normal is like rolling cordwood onto the the pan. Simply click to extend...
The reality that the H4831 is indeed a slower burning powder is exactly why you might be viewing better velocities obtained with that powder, in contrast to what you've observed While using the IMR stuff.
