Given that there does not seem like any "official" Load Data in existence for this Load, can several of you supply a starting point with this combination and factors to think about when Doing the job this Load up?
H4831 will function inside the Swift although not true nicely. You may in no way have the pressures you would like for consistency While using the .223. 760, or H414 will likely be improved but for some rationale I ain't the most significant lover of most ball powders.
It is really most likely that no further discussion is necessary, wherein scenario we suggest setting up a new thread. If even so you are feeling your response is needed you could still do so.
Using the 154 grain Hornady SP from the 280, H4831 gave me good groups and very good velocity, but Rottweil R905 has a substantially bigger velocity and offers marginally better precision. With Swift 150 grain Sciroccos inside the 7mm RM, H4831SC gave great precision and velocity, but RL22 was marginally better. Consequently, in Each and every of these circumstances I went with One more powder, but I will surely loathe to divest myself of your H4831.
Thornton, CO Source of H4831SC is beginning to dwindle down as well so get what you need for your personal new load I'd advise. Could possibly be all of absolutely nothing should they restock every thing Soon but These powders are owning transport regulation troubles.
Liberalism; The impossible however acknowledged notion that it is entirely achievable to choose up a turd with the clear conclusion.
I'm working with it using a 210 Berger. In my rifle, H1000 was not as accurate. RL22 did very well but I was slightly concerned about temp steadiness. I believe I'm at seventy two grains and obtain all over 2850ish fps

dioni.a.312 stated: In my practical experience the one actual distinction would be that the shortcut meters much better through reloading devices. When it's loaded theres h4831sc load data no useful distinction. I have heard the shortcut may have a little little bit quicker burn off price but it seems insignificant. Click on to expand...

Run your load up with the specific powder (sc or regular) and lot you are using however. Very same burn up price doesn't mean it will eventually behave "accurately" a similar. I've noticed more than a hundred fps distinction between sc and mil-surp plenty of H4831.
It's been a bit, but I did get some 4831 SC to test. Located a node and shot some teams. I shot a .6 5 shot group nowadays. It is a little slower than H1000, but shoots very good. Many thanks for the advice, It is really excellent to recognize that I've obtained options when one particular or one other powder is dried up.
Can I believe that H4831 may be substituted for H4831sc ? I am aware the physical variation but will it affect the burn up or velocity? I do think not but I am not one hundred% sure.
I found that my 7mag 160 partitions have been sub MOA with 4831sc with low to min costs. I’m chatting 2700 (probably 2800) fps, it absolutely was a small 60s grain cost within a Norma circumstance. Not what I h4831sc used to be searching for, but correct nonetheless.
