I gave up on it and went to other powder in the event the new powder was acquiring far more force and was slower than the old stuff. I do not remember if I even attempted regular h4831 or not; I am pondering not.
They are the same detail, but H4831 sc is Slash shorter so it can pack right into a situation simpler then the conventional, and in some instances like our 7mm rem mag it permits us to add more powder then just the traditional H4831.
The truth that the H4831 is in fact a slower burning powder is specifically why you might be seeing larger velocities received with that powder, versus Everything you've noticed While using the IMR things. Also good powder, but fairly greater suited to somewhat lesser cases using a bit significantly less potential.
Warning employing SC or SSC designed loads with lengthy Reduce, back off and work up. Use Harmless loading tactics.
IMR powders also preform properly for me with a person notable exception. Every one of the chrongraphing I have completed with them indicates the velecity is consistant previously mentioned 32 levels but begins to vary after the temp starts to drop. The closer to zero I get the greater they vary. I've viewed as much as 250 fps in a 10 shot string with my 243 and 223 inside the Winter season time all over listed here. Have h4831sc load data not witnessed this with many of the other powders.

I do not like to work up a load employing one great deal of powder and afterwards have to work up again simply because I run out and possess to start out utilizing a new ton quantity.
You may either: one) Keep on and have the products listed beneath automatically faraway from your purchasing cart:
Any load data to assistance that? My initial believed is it isn't h4831sc load data likely to burn all the way and velocities will probably be sluggish and everywhere. May very well be a pleasant fireworks display!
locutus claimed: I even now have a superb stockpile of H450, the ball powder equivalent of 4831, which flows via my powder steps smoothly.
If there is not any load data it is actually simply because this h4831sc powder isn't ideal for this cartridge. Typically one particular will not find 1 powder to fit all cartridges, and the family of cartridges with The actual powder (4831SC) that you'll be inquiring about isn't going to operate.

The "SC" means Quick Cut. I haven't discovered a difference between both powder dut I don't Imagine I'd blend them.
Some of the outdated Lyman data just outlined IMR 4831, which was surplus military services powder and now newer mfg as H4831.
The point that the H4831 is indeed a slower burning powder is precisely why you're viewing larger velocities acquired with that powder, rather than That which you've viewed While using the IMR things.
