I gave up on it and went to other powder in the event the new powder was creating extra force and was slower in comparison to the aged stuff. I don't try to remember if I even attempted standard h4831 or not; I'm considering not.
When it comes to bench relaxation matches, Hodgdon® rifle powders have posted much more wins than all other propellants combined. A wonderful extruded powder, it flows accurately and with ease through actions and provides match-grade precision when put to implement.
What's the difference? Compression. With no Severe/large compression related to the very long grain 7828, the strain curve was altered and also the load fell apart.
Minnesota H4831SC is my drop by within the 7mm Rem Mag, but I'm saving the minor I've still left for fall 2021. I would start off small and work your way up, depending on what load data you evaluate for this combo the min/max loads are everywhere in the board.
My working experience is that the SC and SSC loaded to exactly the same excess weight given that the prolonged Reduce demonstrates a lowered velocity.
I understand, tough instances. H4831SC will certainly do the job, I just didn't like the situation density when loaded prolonged. I don't keep in mind powder cost off the highest of my head but I was launching a Berger 168gr VLD at 3,000fps that is the place I typically purpose to be. With your circumstance utilizing what you have (and what I should have completed) I might get started h4831sc with the top on the bearing surface in the bullet suitable with the shoulder/neck junction, and flirt with extending seating depths from there as soon as you find a velocity h4831sc load data node.
I don't love to work up a load utilizing just one large amount of powder after which have to operate up once again simply because I run out and also have to begin employing a new lot amount.
Anyhow, I planned to give some 7828SC a attempt to decrease many of the compression. What a blunder, I could not get this powder to shoot properly or produce the velocities I get with regular 7828.
Any load data to support that? My very first imagined is it isn't really likely to burn the many way and velocities are going to be sluggish and all over the place. May very well be a good fireworks Screen!
locutus reported: I continue to have a great stockpile of H450, the ball powder equivalent of 4831, which flows by way of my powder measures effortlessly.
I required a little much more myself so I went forward and grabbed the 8lb jug being covered for quite a while (and have lots of the exact same lot of powder).
It can be likely that no more dialogue is necessary, during which situation we recommend commencing a new thread. If nevertheless you feel your reaction is necessary you can however accomplish that.
You could possibly either: 1) Keep on and possess the things outlined beneath mechanically removed from your h4831sc procuring cart:
Obviously, sitting down all over for 20+ many years (I know a guy who continues to be utilizing the H4831 he acquired from the 60s), signifies that burn up fees will most likely improve a smidge, and new manufacture things is going to be a little diverse too.
