I am an actual admirer of the H4831 powder. I get fantastic velocity and accuracy from any caliber I have tried using it in. From your 25-06 up into the 338 it is actually my drop by powder of decision. I try out all types of powders when working up loads, though the H4831 usually appears to arrive out on top for precision and velocity when the case is with the 06 course or greater.
When it comes to bench rest matches, Hodgdon® rifle powders have posted a lot more wins than all other propellants blended. A fine extruded powder, it flows properly and effortlessly through steps and delivers match-quality precision when set to make use of.
You are appropriate They can be exactly the same the SC is brief Slice so it meters better, I do not Assume you can get just regular 4831 anymore
Warning working with SC or SSC made loads with long Reduce, back off and get the job done up. Use Safe and sound loading procedures.
My knowledge is that the SC and SSC loaded to a similar body weight because the long Slice shows a reduced velocity.
I realize, rough instances. H4831SC will definitely perform, I just didn't like the case density when loaded long. I don't don't forget powder cost off the very best of my head but I was launching a Berger 168gr VLD at 3,000fps which is where I usually purpose to generally be. Within your situation utilizing what you have (and what I ought to have performed) I might start with the end of your bearing floor in the bullet suitable with the shoulder/neck junction, and flirt with extending seating depths from there as soon as you discover a velocity node.
Anyone loading 7mm Rem Mag with H4831sc? How are the final results, any data you are able to share? Must also point out I have some ELD-X one hundred seventy five's I would want to check out, When you have facts on that as well.
If you've got some heavier .224" bullets, you could discover a load that works Okay Together with the 4831. The bullets I attempted that were in excess of 70 grains would not stabilize in my rifle, which had the common 14" twist. The 70-grain Speer was the greatest bullet that would stabilize, but it really did that wonderfully. It's a amusing-on the lookout bullet using a rounded nose profile, but it shoots terrific and kills properly. Deer out to about a hundred and fifty yards al went down without delay with rib-cage hits.
WA I'd personally advocate a slower burner that can give much better circumstance density like h4831 vs h4831sc H1000 or IMR 7977, particularly if you're loading heavies very long.
It is humorous how through the years loading innumerable various cartridges in many different rifles that I have not obtained appropriate end outcomes with H-4831 or even the small-Slash version.
Run your load up with the specific powder (sc or frequent) and large amount you will be working with though. Same melt away fee doesn't suggest it'll behave "exactly" a similar. I have noticed over a hundred fps difference between sc and mil-surp lots of h4831 vs h4831sc H4831.
I use 52 grs H4831sc by using a 117gr Hornady BTSP. It is really accurate, gentle mannered, and knocks whitetails down DRT. If it had been me, I'd personally start at 52 gr and operate up.
Both of those provide the Very same burn up rate, shorter Minimize comes h4831sc in helpful For anyone who is at max fill and never at pressure/velocity that you might want you may get much more shortcut inside of a scenario.
Certainly, sitting all over for 20+ several years (I know a guy who remains to be utilizing the H4831 he bought from the 60s), means that burn up premiums will most likely modify a smidge, and new manufacture things will likely be somewhat diverse much too.
