Nevertheless IMR 4831 and H4831SC are diverse powders, you will discover that in several occasions, where one of these is stated the opposite is going to be likewise. Also, you will discover there is a fairly steady partnership in between them with reference to mentioned loads.
They have got carried out identically for me. Like Every person else I rushed to get the more recent SC Edition but have now switched again. Ideally you'd like about one hundred% loading density. For those who have sufficient circumstance capability with the H4831(prolonged) you might be most likely much better off.
The most obvious induce is really a rough/ruff bore. No volume of copper fouling lessening brokers in the powder is going to appropriate this.
Using the 154 grain Hornady SP while in the 280, H4831 gave me very good groups and good velocity, but Rottweil R905 provides a appreciably greater velocity and presents marginally greater precision. With Swift 150 grain Sciroccos inside the 7mm RM, H4831SC gave great precision and velocity, but RL22 was marginally better. Consequently, in Every single of those cases I went with A further powder, but I will surely hate to divest myself from the H4831.
The sole variation as I are aware of it is that the SC was made to function via powder measures improved (which it does). The more time grains usually do not feed effectively in any respect in some steps. Thats my 02 :grin:
Given that there will not seem like any "Formal" Load Data out there for this Load, can some of you provide a starting point with this mix and matters to consider when Doing the job this Load up?
I don't like to work up a load making use of one great deal of powder and afterwards have to operate up yet again for the reason that I operate out and possess to start employing a new lot range.
Actually, It is really h4831 vs h4831sc even a good idea to back again down and operate up safely any time you go from 1 whole lot to a different great deal of a similar powder.
WA I'd advocate a slower burner that could give improved circumstance density like h4831 vs h4831sc H1000 or IMR 7977, particularly when you're loading heavies extended.
locutus mentioned: I even now have a great stockpile of H450, the ball powder equal of 4831, which flows as a result of my powder steps effortlessly.
As to the 4831 vs 4831SC, They can be precisely the same/identical powder cept for grain size. Load data is interchangeable.
It's been a little bit, but I did get some 4831 SC to try. Found a node and shot some groups. I shot a .6 five shot group today. It can be a bit slower than H1000, but shoots very good. Thanks for the advice, it's great to know that I've acquired solutions when one or the opposite powder is dried up.
Can I presume that H4831 might be substituted for H4831sc ? I'm sure the physical distinction but will it influence the burn off or velocity? I feel not but I'm not one hundred% guaranteed.
The container didn't h4831sc provide the "Serious" logo on it. A coworker and I then swapped some powder, And that i wound up with A further pound of H4831SC, this a single With all the "Extraordinary" logo on it.
