This can be designed to be the "check out" powder-or darn near to it- for almost any bottle-necked cartridge a single could handload. It really is the foundation for a great number of pet loads, still I have not been happy with the results.
H4831SC Powder available in stock now. Ballistically, this Extreme Extruded powder is the precise duplicate of H4831. Bodily, it has a shorter grain sizing, as a result, the designation SC or short Minimize. The shorter, much more compact kernels allow the powder to circulation through the powder actions extra easily, assisting to reduce the constant slicing of granules.
4gr of H4831sc and Federal 215 primers. I discovered this combo generates .5MOA teams with velocity about 3020fps away from a 26" barrel. I use this exact powder in my 300wm capturing 180gr supplements, so It really is nice to obtain one particular powder for each.
Run your load up with the particular powder (sc or frequent) and ton you happen to be employing however. Same burn up amount doesn't mean it's going to behave "particularly" the exact same. I have noticed in excess of a hundred fps distinction between sc and mil-surp lots of H4831.
The one variance as I realize it is that the SC was made to work as a result of powder actions far better (which it does). The for a longer time grains tend not to feed effectively whatsoever in some actions. Thats my 02 :grin:
I am aware, tough moments. H4831SC will definitely perform, I just didn't like the case density when loaded long. I do not keep in mind powder charge off the best of my head but I had been launching a Berger 168gr VLD at 3,000fps which can be in which I generally aim to generally be. In the case employing what you have got (and what I must have accomplished) I'd get started with the tip in h4831 vs h4831sc the bearing surface of your bullet appropriate on the shoulder/neck junction, and flirt with extending seating depths from there as soon as you discover a velocity node.
NBTs or Hornady VMax, but Have a very minimal source of Varget, along with a whole lot extra available H4831SC. I shoot 55 gr. loads Virtually solely, mainly because that is definitely just what the rifles shoot the best.
While this might be genuine, there's a good deal additional to it than simply h4831 vs h4831sc not blowing your self up. He couldn't hit prairie pet dogs past about a hundred and fifty yards, so I'm guessing that inconsistent combustion wasn't performing just about anything favorable for his grouping capacity with Those people loads.
I've uncovered the exact reverse to generally be accurate in my gun. H4831SC was the slowest powder with h4831sc one hundred eighty g Accubonds. RL22 was a considerably faster and equally correct powder in my 300 Earn Mag.
It also goes on to state that due to the fshorter grains, that load density may very well be a little bigger.
This really is an more mature thread, you might not receive a reaction, and will be reviving an outdated thread. Make sure you think about developing a new thread.

I realize the H4831SC presents a greater load density But I believe I've enough area in my situation for the normal H4831.
The container did not possess the "Severe" emblem on it. A coworker and I then swapped some powder, and I ended up with An additional pound of H4831SC, this one Using the "Intense" emblem on it.
