That is speculated to be the "head over to" powder-or darn near to it- for nearly any bottle-necked cartridge one could handload. It is the muse for countless pet loads, nonetheless I have never been happy with the outcome.
Naturally, the Hodgdon tech would not endorse my mixing of different large amount figures, but I do think I understand why. It's a litigation-pushed entire world, and several fool would definitely deduce that he could mix H380 and H110 and think of his very own tailor made mixture of powder. What a environment.
This has become the most significant motives reloaders are admonished to work with new data only; and to begin very low anytime you have a fresh large amount of powder. You do not seriously know (Except if the organization lets you know so) that your new wide range of powder was even manufactured at the identical manufacturing unit as being the powder you obtain a several years ago.
I've had a handful of rifles that fouled seriously undesirable. Acquiring all of the copper out was a true PIA until eventually I found Wipe-Out foaming bore cleaner.

It is really very likely that no further discussion is necessary, during which circumstance we suggest starting off a fresh thread. If having said that you really feel your response is needed you could nonetheless do this.
Hodgdon H4831SC (Short Cut) extruded rifle propellant is really a best choice for big sport hunters who use handloader rifles. Introduced within the 1950s, this propellant continues to be enhanced with shorter grain dimensions which will allow improved powder move plus more uniformity.
Actually, It is really even a good idea to back again down and work up securely after you go from a single large amount to another lots of precisely the same powder.
I've observed the precise reverse to become correct in my gun. H4831SC was the slowest powder with a hundred and eighty g Accubonds. RL22 was a much faster and equally correct powder in my 300 Acquire Mag.
Ballistically, this Extraordinary Extruded powder is the exact copy of H4831. Bodily, it's got a shorter grain size, as a h4831 vs h4831sc result, the designation SC or small cut. The shorter, much more compact kernels allow the powder to circulation from the powder steps extra smoothly, helping to alleviate the continual reducing of granules.
As with the 4831 vs 4831SC, These are precisely the same/identical powder cept for grain sizing. Load data is interchangeable.
It's been a bit, but I did get some 4831 SC to test. Observed a node and shot some groups. I shot a .six 5 shot group today. It can be a bit slower than h4831sc H1000, but shoots superior. Thanks for the recommendation, It is superior to realize that I have received possibilities when one particular or the other powder is dried up.
Am i able to suppose h4831sc that H4831 can be substituted for H4831sc ? I do know the Actual physical variation but will it affect the burn up or velocity? I do think not but I'm not one hundred% guaranteed.
IMR4831 and H4831SC are distinctive. The place you may be confusing it and believing that it's shut is H4831 and H4831SC are incredibly similar. All those two are just about a similar besides H4831SC is built to more compact grains so it meters easier.
