I am a true lover with the H4831 powder. I get wonderful velocity and accuracy away from any caliber I have tried using it in. From your 25-06 up on the 338 it is actually my check out powder of choice. I attempt every type of powders when Functioning up loads, even so the H4831 generally seems to come out on leading for accuracy and velocity when the situation is of your 06 course or larger sized.
When it comes to bench relaxation matches, Hodgdon® rifle powders have posted far more wins than all other propellants blended. A wonderful extruded powder, it flows precisely and without difficulty via actions and delivers match-grade precision when place to work with.
It can be possible that no further more dialogue is needed, during which situation we advise commencing a fresh thread. If even so you feel your reaction is needed it is possible to even now achieve this.
Together with the 154 grain Hornady SP inside the 280, H4831 gave me great teams and fantastic velocity, but Rottweil R905 incorporates a substantially greater velocity and gives marginally much better precision. With Swift 150 grain Sciroccos in the 7mm RM, H4831SC gave great accuracy and velocity, but RL22 was marginally better. Consequently, in Each individual of those instances I went with A different powder, but I would certainly despise to divest myself on the H4831.
IMR powders also preform properly for me with a person notable exception. Each of the chrongraphing I have carried out with them suggests the velecity is consistant higher than 32 levels but begins to vary after the temp starts to fall. The nearer to zero I get the greater they change. h4831sc load data I've noticed approximately 250 fps in a 10 shot string with my 243 and 223 while in the winter time close to listed here. Have not found this with several of the other powders.
It is likely that no further more discussion is necessary, in which circumstance we advise beginning a completely new thread. If even so you feel your reaction is required you may nevertheless accomplish that.
Nampa, Idaho In my expertise the sole actual variation is that the shortcut meters superior as a result of reloading tools. As soon as it's loaded theres no purposeful distinction. I have heard the shortcut could possibly have a little little bit more rapidly burn up rate but It appears insignificant.

The primary reason I switched from IMR 4831 to H4831 was to benefit from the temperature insensitivity of a Hodgdon Serious powder.
The 55grs is all that I shoot h4831sc from my swift. Other manuals I think that they have got slowed down the swift to show that their rifles are better. It bug the hell away from me. I realize better. This is exactly why I don't at any time throw out my more mature manuals. I do obtain new handbook continuously to stay up on new chambers and there loading. I exploit this 39grs in summers @ one hundred+ levels with no problems.
Operate your load up with the particular powder (sc or typical) and good deal you're using nevertheless. Exact burn off charge doesn't mean it will eventually behave "particularly" precisely the same. I have observed more than a hundred fps difference between sc and mil-surp plenty of H4831.
The "SC" means Short Minimize. I haven't seen a distinction between either powder dut I don't Imagine I'd mix them.
Am i able to believe that H4831 is usually substituted for H4831sc ? I'm sure the Actual physical difference but will it impact the burn or velocity? I think not but I'm not a hundred% guaranteed.
I could stack em in a single gap but I wasn’t satisfied with the velocity. Soon after months, I got Blessed and caught some H1000 on the internet h4831 vs h4831sc and of course compensated just a little further. The pretty following week at a gun show a man experienced an entire scenario of H1000 for $forty per 1lb. I forget about just how much, but While using the H1000 I’m now pushing a 160gr about 3200 and it’s a delicate load.
