What is actually Everybody receiving great precision with for 180gr supplements and 4831? Just seeking a starting point so I don't waste lots of parts. Many thanks for the help!
H4831 will perform while in the Swift but not serious effectively. You will never ever receive the pressures you require for regularity with the .223. 760, or H414 will likely be improved but for some cause I ain't the greatest enthusiast of most ball powders.
You will be accurate They can be precisely the same the SC is brief Slice so it meters better, I do not Imagine you can find just typical 4831 any more
Minnesota H4831SC is my head over to while in the 7mm Rem Mag, but I'm conserving the tiny I have remaining for fall 2021. I'd start low and do the job your way up, based upon what load data you evaluate for this combo the min/max loads are all around the board.
My knowledge would be that the SC and SSC loaded to precisely the same fat because the extended cut displays a decreased velocity.
I know, tough periods. H4831SC will definitely function, I just failed to like the situation density when loaded long. I do not don't forget powder charge off the very best of my head but I had been launching a Berger 168gr VLD at 3,000fps which can be where I ordinarily intention to generally be. As part of your situation utilizing what you may have (and what I should have done) I might begin with the top on the bearing area of the bullet suitable in the shoulder/neck junction, and flirt with extending seating depths from there as you discover a velocity node.

and it is advisable to spend money on some new load data guides. powder composition and chemistry h4831sc can does change over the years. 4831 powder of a long time in the past isn't really similar as what exactly is available. that is certainly why somebody seriously interested in reloading properly will likely have the most current load data books to make reference to.
The h4831sc main reason I switched from IMR 4831 to H4831 was to take full advantage of the temperature insensitivity of the Hodgdon Extraordinary powder.
Ballistically, this Intense Extruded powder is the exact copy of H4831. Physically, it has a shorter grain measurement, thus, the designation SC or short Reduce. The shorter, a lot more compact kernels allow the powder to stream from the powder steps extra effortlessly, assisting to ease the constant cutting of granules.
Despite the similarity in nomenclature, They are entirely distinctive powders, with IMR 4831 currently being significantly more quickly than the Hodgdon variants. Will not address them as precisely the same powder, since they most definitely are usually not.
It is really likely that no additional discussion is required, during which situation we advise starting up a different thread. If having said that you really feel your response is required you are able to nonetheless do so.
rayporter claimed: i hardly ever noticed a distinction apart from the typical is like rolling cordwood onto the the pan. Click to grow...
This looks like a very good place to divulge a little bit more info on Hodgdon, H4831 exclusively...I once had a pound of H4831SC sit about the h4831sc load data shelf for a number of a long time. It had been procured just before Hodgdon started publicizing the "Serious" line of powders, of which the H4831s are an element.
