This is certainly supposed to be the "drop by" powder-or darn near it- for just about any bottle-necked cartridge a single could handload. It is the foundation for countless pet loads, still I haven't been content with the final results.

I have utilised H4831 (and H4831SC), and I utilize it. There aren't numerous cartridges that I utilize it for as I look normally to gravitate to other powders. Even so, I can not state that it does not do the job. It is simply that Several other powders get the job done superior for any presented cartridge. For example, from the 280, H4831 gave me great velocity and really good groups with Nosler 140 AB. Nonetheless, RL19 was marginally much better in accuracy, even though the velocity was almost similar.

This has become the major reasons reloaders are admonished to make use of new data only; and to begin lower when you get a new great deal of powder. You don't actually know (Unless of course the business lets you know so) that your new lot of powder was even built at the same manufacturing unit given that the powder you got a several years in the past.

IMR powders also preform well for me with a person noteworthy exception. Every one of the chrongraphing I have finished with them signifies the velecity is consistant above 32 levels but starts to change as soon as the temp starts to fall. The closer to zero I get the more they vary. I have seen just as much as 250 fps in a ten shot string with my 243 and 223 within the Wintertime time close to in this article. Have not found this with several of the other powders.

I realize, tough occasions. H4831SC will certainly function, I just did not like the case density when loaded extensive. I don't recall powder charge off the highest of my head but I had been launching a Berger 168gr VLD at 3,000fps and that is exactly where I commonly aim to generally be. Inside your scenario employing what you've (and what I must have finished) I would start with the tip of the bearing area of the bullet proper for the shoulder/neck junction, and flirt with extending seating depths from there as you find a velocity node.

Hodgdon H4831SC (Short Reduce) extruded rifle propellant is really a major option for huge sport hunters who use handloader rifles. Launched in the fifties, this propellant has become improved with shorter grain dimensions which makes it possible for much better powder move plus much more uniformity.

Anyhow, I desired to give some 7828SC a try and cut down a number of the compression. What a mistake, I could not get this powder to shoot correctly or deliver the velocities I get with conventional 7828.

Presently making use of IMR 4831 within a 300WSM, and see the H4831sc is a popular option for this caliber and yields a little bit more velocity. In addition to it remaining shorter Slash, what's the difference in both of h4831 vs h4831sc these powders, and may I swap to H4831sc?

Confirm YOUR AGE Particular states prohibit promotion or advertising and marketing of firearms, ammunition, and connected firearm components to minors.

Despite the similarity in nomenclature, They are absolutely diverse powders, with IMR 4831 currently being substantially faster as opposed to Hodgdon variants. Never deal with them as the identical powder, because they most certainly are not.

Right after examining this text (and lots of Many others, but this a single is easily the most data driven h4831sc load data with various accredited shooters) I've stopped worrying about touching or currently being within a magical distance within the lands, and started loading the place I could improve several components of a load. Just my .02, hopefully you may get something to work for ya.

Southwest Idaho I attempted H4831sc in my three hundred WM but had significantly better speed and accuracy with H1000. I would somewhat use a slower burning powder with h4831sc load data 215g capsules.

The reality that the H4831 is indeed a slower burning powder is exactly why you happen to be seeing increased velocities attained with that powder, instead of That which you've seen Together with the IMR things.
