Considering that there will not look like any "Formal" Load Data around for this Load, can a number of you supply a starting point with this mixture and items to think about when Doing the job this Load up?
They've got done identically for me. Like Anyone else I rushed to find the newer SC Model but have now switched back. Preferably you'd like about one hundred% loading density. For those who have adequate case ability for the H4831(extensive) you will be probably far better off.
The truth that the H4831 is without a doubt a slower burning powder is exactly why you happen to be viewing bigger velocities attained with that powder, as opposed to what you've seen Using the IMR stuff. Also great powder, but relatively better suited to slightly lesser conditions having a little bit considerably less capacity.
With the 154 grain Hornady SP from the 280, H4831 gave me fantastic teams and good velocity, but Rottweil R905 features a substantially larger velocity and gives marginally superior accuracy. With Swift 150 grain Sciroccos while in the 7mm RM, H4831SC gave exceptional precision and velocity, but RL22 was marginally greater. As a result, in Each and every of such circumstances I went with An additional powder, but I would certainly loathe to divest myself on the H4831.
IMR powders also preform properly for me with just one noteworthy exception. Many of the chrongraphing I've finished with them indicates the velecity is consistant over 32 levels but begins to range as soon as the temp starts to fall. The closer to zero I get the more they range. I have seen approximately 250 fps in a ten shot string with my 243 and 223 h4831sc while in the Wintertime time close to right here. Haven't observed this with a lot of the other powders.
Because there will not look like any "Formal" Load Data out there for this Load, can a few of you supply a place to begin with this mix and things to think about when Functioning this Load up?
Nampa, Idaho In my working experience the only real authentic variance is that the shortcut meters much better via reloading gear. After It really is loaded theres no functional change. I've read the shortcut can have a small little bit more rapidly burn up level but it seems insignificant.
In truth, It truly is even a good idea to again down and operate up safely when you go from one particular whole lot to a different wide range of the identical powder.
Presently making use h4831sc of IMR 4831 inside of a 300WSM, and find out the H4831sc is a popular option for this caliber and yields a little bit more velocity. Besides it staying limited Slice, what is the difference in both of these powders, and should I change to H4831sc?
You might have to generate a couple of extra posts to have cleared to carry out PM's. After you get to that position I would publish inside the categorized reloading segment to find out if any individual is near you for a trade. Simply click to extend...
Despite the similarity in nomenclature, They are completely distinct powders, with IMR 4831 remaining substantially speedier compared to the Hodgdon variants. Don't deal with them as a similar powder, since they most definitely will not be.
Right after reading through this post (and a lot of Many others, but this a person is considered the most data driven with various accredited shooters) I have stopped worrying about touching or being in just a magical distance within the lands, and started loading in which I could improve a number h4831sc of elements of a load. Just my .02, ideally you can get a thing to operate for ya.
Several of the outdated Lyman data just listed IMR 4831, which was surplus army powder and now newer mfg as H4831.
NBTs or Hornady VMax, but Use a restricted supply of Varget, as well as a good deal far more offered H4831SC. I shoot 55 gr. loads Nearly solely, due to the fact which is what the rifles shoot the most beneficial.
