I have experienced a number of rifles that fouled actually lousy. Finding the many copper out was a real PIA until I discovered Wipe-Out foaming bore cleaner.
IMR powders also preform nicely for me with one particular notable exception. Each of the chrongraphing I've finished with them indicates the velecity is consistant previously mentioned 32 levels but begins to change once the temp begins to fall. The nearer to zero I get the greater they vary. I have noticed approximately 250 fps in a ten shot string with my 243 and 223 from the winter time close to below. Haven't viewed this with a lot of the other powders.
Since there would not seem like any "Formal" Load Data to choose from for this Load, can a number of you provide a place to begin with this combination and matters to think about when working this Load up?
I am utilizing it which has a 210 Berger. In h4831sc my rifle, H1000 was not as accurate. RL22 did nicely but I was a little concerned about temp balance. I think I am at 72 grains and have all around 2850ish fps
If you've some heavier .224" bullets, you could look for a load that works Okay Along with the h4831sc 4831. The bullets I tried that were around 70 grains wouldn't stabilize in my rifle, which experienced the standard 14" twist. The 70-grain Speer was the most significant bullet that will stabilize, but it really did that superbly. It is a amusing-searching bullet that has a rounded nose profile, however it shoots wonderful and kills properly. Deer out to about a hundred and fifty yards al went down immediately with rib-cage hits.
The primary reason I switched from IMR 4831 to H4831 was to take full advantage of the temperature insensitivity of a Hodgdon Serious powder.
locutus explained: I continue to have a great stockpile of H450, the ball powder equivalent of 4831, which flows by means of my powder actions efficiently.
I've had identical expertise with H4350. For me, some ball powders will never shoot effectively with nearly anything except Fed215's. Some elements just don't Engage in very well with other. Looks like you've decided on three superior powders, I would count on no less than one of these to shoot.
Just after looking at this text (and plenty of Other individuals, but this a single is the most data pushed with several accredited shooters) I've stopped stressing about touching or getting within a magical length from your lands, and started loading where by I could enhance numerous components of a load. Just my .02, ideally you can get a little something to work for ya.
Nevertheless IMR 4831 and H4831SC are different powders, you h4831sc will discover that in lots of occasions, where one of them is outlined another is going to be in addition. Also, you will discover there is a reasonably consistent partnership among them with reference to detailed loads.
Obviously, sitting all over for twenty+ decades (I understand a guy who continues to be using the H4831 he purchased from the 60s), ensures that melt away rates will probably alter a smidge, and new manufacture stuff will be marginally diverse far too.
