I am a real admirer of your H4831 powder. I get fantastic velocity and accuracy away from any caliber I've tried it in. From your twenty five-06 up to the 338 it really is my head over to powder of selection. I consider all kinds of powders when Doing the job up loads, however the H4831 generally appears to arrive out on prime for accuracy and velocity when the case is in the 06 class or more substantial.
I've utilized H4831 (and H4831SC), And that i utilize it. There usually are not numerous cartridges which i use it for as I appear normally to gravitate to other powders. Even so, I am unable to state that it doesn't do the job. It is just that Various other powders get the job done superior for your presented cartridge. For instance, while in the 280, H4831 gave me fantastic velocity and really wonderful teams with Nosler 140 AB. Even so, RL19 was marginally greater in accuracy, though the velocity was almost similar.
It's likely that no more dialogue is required, wherein scenario we endorse commencing a fresh thread. If nevertheless you really feel your response is needed you can continue to do so.
Run your load up with the precise powder (sc or typical) and lot you will be making use of though. Identical burn up rate doesn't mean it will eventually behave "precisely" the identical. I've observed above 100 fps difference between sc and mil-surp numerous H4831.
Thornton, CO Supply of H4831SC is beginning to dwindle down much too so get what you require for the new load I'd counsel. Might be all of practically nothing if they restock every little thing Soon but These powders are getting transportation regulation issues.
Any load data to support that? My to start with considered is it is not about to burn up every one of the way and velocities is going to be sluggish and everywhere. May be a nice fireworks display!
I am working with it that has a 210 Berger. In my rifle, H1000 was not as accurate. RL22 did well but I had been slightly concerned about temp stability. I do think I am at seventy two grains and acquire about 2850ish fps
and you might want to invest in some new load data textbooks. h4831sc load data powder composition and chemistry can does transform over the years. 4831 powder of many years in the past just isn't same as what's now available. that's why someone seriously interested in reloading safely and securely should have one of the most present-day load data guides to refer to.
The primary reason I switched from IMR 4831 to H4831 was to take advantage of the temperature insensitivity of a Hodgdon Excessive powder.
Ballistically, this Intense Extruded powder is the precise duplicate of H4831. Bodily, it's a shorter grain dimensions, hence, the designation SC or short cut. The shorter, much more compact kernels allow the powder to flow throughout the powder actions extra smoothly, helping to relieve the regular reducing of h4831sc load data granules.
Kansas Town, MO I would grab no matter what is out there at this time. I’ve used the two however with my drop by load and didn’t see something distinct efficiency smart.
This is certainly an Serious h4831sc extruded propellant and delivers heightened insensitivity to cold and hot temperatures.
Can I suppose that H4831 might be substituted for H4831sc ? I am aware the Bodily variance but will it have an impact on the melt away or velocity? I feel not but I am not one hundred% positive.
IMR4831 and H4831SC are diverse. Where you could be bewildering it and thinking that it can be close is H4831 and H4831SC are incredibly identical. These two are essentially exactly the same besides H4831SC is built to smaller grains so it meters less complicated.
