Considering that there isn't going to appear to be any "official" Load Data out there for this Load, can many of you deliver a place to begin with this mixture and items to consider when Functioning this Load up?

Ballistically, Hodgdon H4831 SC Powder is the exact duplicate of H4831. Physically, it's a shorter grain size, thus, the designation SC or shorter Minimize. The shorter, more compact kernels enable the powder to flow from the powder measures a lot more effortlessly, helping to reduce the continuous slicing of granules.

The most obvious result in is really a tough/ruff bore. No number of copper fouling lowering agents from the powder will probably right this.

Caution employing SC or SSC produced loads with lengthy cut, again off and perform up. Use Secure loading techniques.

IMR powders also preform properly for me with a single noteworthy exception. Every one of the chrongraphing I have finished with them implies the velecity is consistant previously mentioned 32 degrees but begins to vary when the temp starts to fall. The closer to zero I get the greater they fluctuate. I've witnessed around 250 fps in a ten shot string with my 243 and 223 within the Wintertime time close to right here. Haven't observed this with some of the other powders.

Given that there would not seem like any "Formal" Load Data on the market for this Load, can many of you present a starting point with this mixture and things to think about when Doing the job this Load up?

NBTs or Hornady VMax, but Have got a limited provide of Varget, and also a lot a lot more offered H4831SC. I shoot fifty five gr. loads almost exclusively, since that is definitely just what the rifles shoot the most beneficial.

While this is most likely correct, there is a good deal more to it h4831sc than simply not blowing oneself up. He could not hit prairie canine beyond about one hundred fifty yards, so I am guessing that inconsistent combustion wasn't executing anything at all favorable for his grouping means with Individuals loads.

WA I would suggest a slower burner that may give superior circumstance density like H1000 or IMR 7977, especially if you're loading heavies lengthy.

It truly is amusing how over time loading plenty of unique cartridges in numerous rifles that I have never gained appropriate conclusion benefits with H-4831 or even the brief-cut Variation.

Despite the similarity in nomenclature, They are totally various powders, with IMR h4831sc load data 4831 getting considerably more rapidly in comparison to the Hodgdon variants. You should not treat them as precisely the same powder, since h4831sc they most unquestionably aren't.

NBTs or Hornady VMax, but have a restricted offer of Varget, and a whole lot extra accessible H4831SC. I shoot fifty five gr. loads Pretty much exclusively, since that is definitely just what the rifles shoot the very best.

Can I assume that H4831 is often substituted for H4831sc ? I realize the Actual physical variation but will it impact the melt away or velocity? I believe not but I am not 100% absolutely sure.

I sawed just one in fifty percent to check out how thick the jackets have been, they usually had been conveniently two times as thick to be a 50-grain hollow place was. Ditto for the sixty four-grain Power Level, as these bullets are developed for deer, not prairie pet dogs or woodchucks. You now know every little thing I understand about the 22-250 and slow-burning powders, and I don't know nearly anything whatsoever with regards to the 223. I question that you're going to get wherever with that cartridge and 4831, but let's know how it goes.
