Considering the fact that there isn't going to appear to be any "official" Load Data available for this Load, can many of you supply a place to begin with this combination and points to think about when Performing this Load up?
They're the exact same point, but H4831 sc is Minimize shorter so it'll pack right into a case less difficult then the normal, and in some cases like our 7mm rem mag it permits us to incorporate extra powder then just the normal H4831.
The obvious cause is actually a rough/ruff bore. No quantity of copper fouling minimizing brokers from the powder will almost certainly right this.
Run your load up with the precise powder (sc or typical) and lot you will be making use of nevertheless. Identical melt away charge does not imply it's going to behave "accurately" a similar. I've viewed more than one hundred fps difference between sc and mil-surp many H4831.
In any case, I knew the two lbs of H4831SC applied the exact same data, but I did not know no matter whether there was something various amongst a pound of powder labeled "Excessive" and one not so labeled. A connect with to Hodgdon confirmed they have been in reality similar and the sole variation was the logo about the label.
It truly is possible that no further more discussion is necessary, through which case we recommend starting a fresh thread. If nevertheless you really feel your response is necessary you may nevertheless do so.
Hodgdon H4831SC (Limited Minimize) extruded rifle propellant is actually a major option for significant sport hunters who use handloader rifles. Released while in the 1950s, h4831sc load data this propellant continues to be enhanced with shorter grain dimensions which lets better powder stream plus much more uniformity.
excaliber explained: I've found the exact reverse to be real in my gun. H4831SC was the slowest powder with 180 g Accubonds. RL22 was a considerably faster and h4831sc Similarly accurate powder in my 300 Earn Mag.
dioni.a.312 mentioned: In my practical experience the one serious difference is that the shortcut meters far better through reloading tools. The moment It really is loaded theres no useful variance. I have listened to that the shortcut may have a small bit quicker burn up amount but It appears insignificant. Click on to extend...
The 55grs is everything I shoot from my swift. Other manuals I feel that they have got slowed down the swift to point out that their rifles are improved. It bug the hell away from me. I realize much better. This is exactly why I don't at any time toss out my older manuals. I do obtain new manual all the time to remain up on new chambers and there loading. I exploit this 39grs in summers @ a hundred+ levels with no issues.
I have experienced comparable encounter with H4350. For me, some ball powders would not shoot properly with something apart from Fed215's. Some elements just You should not Engage in nicely with other. Appears like you've got picked 3 superior h4831sc powders, I'd personally assume at the least one of them to shoot.
It's possible that no even further discussion is required, wherein scenario we advise starting off a whole new thread. If nonetheless you feel your reaction is required you can however achieve this.
Can I assume that H4831 could be substituted for H4831sc ? I do know the Actual physical change but will it impact the burn up or velocity? I believe not but I'm not 100% sure.
The container did not contain the "Excessive" logo on it. A coworker And that i then swapped some powder, and I wound up with another pound of H4831SC, this just one With all the "Extreme" brand on it.
