I gave up on it and went to other powder if the new powder was producing extra pressure and was slower in comparison to the aged things. I do not recall if I even tried using frequent h4831 or not; I'm pondering not.
Ballistically, Hodgdon H4831 SC Powder is the exact duplicate of H4831. Physically, it has a shorter grain sizing, as a result, the designation SC or short Minimize. The shorter, a lot more compact kernels allow the powder to circulation through the powder steps more efficiently, assisting to alleviate the regular chopping of granules.
The obvious cause is often a rough/ruff bore. No volume of copper fouling reducing agents from the powder will correct this.
Operate your load up with the specific powder (sc or normal) and great deal you're using though. Exact same burn level doesn't suggest it'll behave "precisely" exactly the same. I have witnessed more than a hundred fps difference between sc and mil-surp numerous H4831.
In any case, I realized The 2 kilos of H4831SC applied the exact same data, but I didn't know whether there was everything diverse involving a pound of powder labeled "Serious" and just one not so labeled. A simply call to Hodgdon verified they had been the truth is similar and the sole distinction was the logo over the label.
I have employed H4831 and H4831SC in my 260 Rem without variation. The one thing could be the small Slash provides you with a bit more Room. Excellent luck!gun)
You might have for making several extra posts to have cleared to complete PM's. When you finally get to that standing I'd write-up while in the categorized reloading portion to view if anybody is in your area for any trade.
and you may want to invest in some new load data guides. powder composition and chemistry can does modify through the years. 4831 powder of decades in the past just isn't similar h4831sc load data as what is currently available. that's why anyone seriously interested in reloading safely should have quite possibly the most latest load data guides to check with.
Along with the small Slash Variation powder comes approximately the base on the decreased shoulder so I however have many place.
Confirm YOUR AGE Particular states prohibit promotion or promoting of firearms, ammunition, and associated firearm factors to minors. We’d like to make certain you’re eighteen a long time of age or more mature prior to permitting you to buy our site. Will you be 18 several years of age or older?
Run your load up with the particular powder (sc or frequent) and ton that you are making use of though. Same burn up rate doesn't suggest it is going to behave "exactly" the identical. I have found in excess of 100 fps difference between sc and mil-surp a lot of H4831.
This is certainly an Severe extruded propellant and offers heightened insensitivity to cold and hot temperatures.
Each have the Similar burn up price, shorter Slice comes in helpful Should you be h4831 vs h4831sc at max fill and not at tension/velocity that you'd like you will get much more shortcut in a scenario.
I could stack em in a single gap but I wasn’t happy with the velocity. Soon after months, I acquired Fortunate and caught some H1000 on the web and naturally paid a little extra. The pretty upcoming h4831sc 7 days at a gun show a man had a whole circumstance of H1000 for $forty per 1lb. I forget exactly how much, but While using the H1000 I’m now pushing a 160gr about 3200 and it’s a delicate load.
