However IMR 4831 and H4831SC are distinctive powders, you can find that in several circumstances, wherever one of them is shown the opposite are going to be also. Also, you will find there is a reasonably consistent partnership among them with reference to shown loads.

I'd say you would be much better off looking at if an individual could be willing to trade you some Varget for your personal H4831SC.

What's the main difference? Compression. With no Intense/significant compression connected to the long grain 7828, the strain curve was altered and the load fell apart.

Yes it is possible to. They're the exact same exact powder although the SC powder is simply Lower shorter so it meters far better.

IMR powders also preform well for me with just one notable exception. All the chrongraphing I've completed with them implies the velecity is consistant previously mentioned 32 degrees but begins to fluctuate once the temp begins to drop. The nearer to zero I get the greater they fluctuate. I have seen just as much as 250 fps in a 10 shot string with my 243 and 223 from the winter time all over right here. Haven't noticed this with a number of the other powders.

Liberalism; The unattainable still acknowledged Idea that it's entirely achievable to choose up a turd via the clean stop.

i've utilized both equally and made h4831sc use of the very same rates and possess not been able to tell any noticable variations with efficiency. the SC Edition meters just a little smoother is about all. any remarks??

Anyhow, I wanted to give some 7828SC a try and cut down many of the compression. What a blunder, I couldn't get this powder to shoot precisely or produce the velocities I get with typical 7828.

With the limited cut Model powder will come approximately the base with the reduce shoulder h4831sc so I however have plenty of place.

You could have to create a number of extra posts to acquire cleared to try and do PM's. Once you get to that standing h4831sc I would write-up while in the categorised reloading section to find out if any individual is in your area for just a trade. Click to broaden...

Operate your load up with the particular powder (sc or typical) and great deal you will be employing nevertheless. Identical burn off rate doesn't suggest it can behave "precisely" precisely the same. I've observed around one hundred fps difference between sc and mil-surp many H4831.

This is often an Excessive extruded propellant and provides heightened insensitivity to cold and warm temperatures.

I usually normally obtain the sc Variation. Utilizing a powder evaluate it hangs up much less as a consequence of shorter kernels and I feel will allow a lot more dependable metering so significantly less time you are taking trickling in the last little bit of demand to produce body weight. So essentially the SC will save you situations

This looks as if a fantastic location to divulge a little more info on Hodgdon, H4831 specifically...I at the time experienced a pound of H4831SC sit about the shelf for quite a few a long time. It was purchased right before Hodgdon started publicizing the "Severe" line of powders, of which the H4831s are a part.
