I gave up on it and went to other powder when the new powder was creating far more stress and was slower compared to old stuff. I don't remember if I even tried using frequent h4831 or not; I am thinking not.
I've utilized H4831 (and H4831SC), And that i use it. There usually are not a lot of cartridges which i use it for as I look often to gravitate to other powders. Nevertheless, I am unable to say that it would not perform. It is simply that Various other powders function improved for any offered cartridge. For instance, from the 280, H4831 gave me great velocity and very fine groups with Nosler one hundred forty AB. Nevertheless, RL19 was marginally superior in accuracy, however the velocity was virtually equivalent.
It can be probable that no even more dialogue is required, in which circumstance we advocate beginning a new thread. If having said that you feel your reaction is required you could even now do so.
With the 154 grain Hornady SP while in the 280, H4831 gave me excellent teams and excellent velocity, but Rottweil R905 contains a noticeably higher velocity and offers marginally far better precision. With Swift 150 grain Sciroccos during the 7mm RM, H4831SC gave fantastic precision and velocity, but RL22 was marginally much better. For that reason, in Each and every of these cases I went with another powder, but I would definitely despise to divest myself on the H4831.
IMR powders also preform nicely for me with one noteworthy exception. The many chrongraphing I have finished with them suggests the velecity is consistant previously h4831sc mentioned 32 levels but starts to differ when the temp starts to drop. The closer to zero I get the more they differ. I have viewed up to 250 fps in a ten shot string with my 243 and 223 from the winter time all over listed here. Have not seen this with a few of the other powders.
Did you ever check out H4831sc in you 300wsm and 215 bergers. I've a 300wsm now. Capturing 180g with H4350 at 2940fps with conventional chamber. Pondering what to expect with 215 bergers with H4331sc?
I do not like to work up a load working with a person number of powder after which you can have to work up yet again simply because I run out and h4831sc load data possess to start utilizing a new ton variety.
The SC or SSC specified powders Usually allow for bigger load density, to help you commonly get a little additional powder in the offered situation when employing compressed loads. Use of a drop tube can further more boost this advantage.
You could possibly h4831sc load data both: 1) Continue on and possess the firearm(s) stated below quickly removed from your shopping cart:
Why would I point out this? Precisely what is my place? I am not sure that there is a authentic legitimate stage besides what is well-known with most hasn't been preferred with me in any way in these instances. Do I just have a powder jinx or one thing? Only to tell you about how insane I really am, tomorrow I am assortment screening a good friends new .
Operate your load up with the precise powder (sc or frequent) and large amount you are using though. Same melt away level does not imply it can behave "particularly" the exact same. I've noticed more than a hundred fps distinction between sc and mil-surp a lot of H4831.
NBTs or Hornady VMax, but Use a limited provide of Varget, in addition to a good deal extra obtainable H4831SC. I shoot 55 gr. loads Practically completely, simply because that is definitely just what the rifles shoot the most effective.
You might either: 1) Carry on and have the items outlined beneath immediately removed from your shopping cart:
The point that the H4831 is certainly a slower burning powder is specifically why you're observing higher velocities acquired with that powder, versus Everything you've viewed Using the IMR things.
