I picked up a 50ct. box of one hundred sixty Nosler Accubonds, but I'm hesitant to burn the powder and projectiles on workup when all I have is fifty bullets. But I actually need to locate a bullet from the 160 class that my more mature rifle likes.
H4831 will function during the Swift but not actual properly. You can expect to by no means get the pressures you will need for consistency With all the .223. 760, or H414 is going to be greater but for a few explanation I ain't the greatest admirer of most ball powders.
4gr of H4831sc and Federal 215 primers. I discovered this combo creates .5MOA groups with velocity about 3020fps outside of a 26" barrel. I exploit this identical powder in my 300wm taking pictures 180gr drugs, so It is nice to get just one powder for both of those.
Operate your load up with the specific powder (sc or common) and great deal you might be using however. Exact same burn off rate doesn't suggest it will eventually behave "exactly" the exact same. I have observed about 100 fps difference between sc and mil-surp numerous H4831.
IMR powders also preform nicely for me with 1 notable exception. All of the chrongraphing I've carried out with them indicates the velecity is consistant higher than 32 levels but begins to vary after the temp starts to drop. The nearer to zero I get the greater they differ. I have found just as much as 250 fps in a 10 shot string with my 243 and 223 within the Wintertime time close to right here. Haven't viewed this with several of the other powders.
I've applied H4831 and H4831SC in my 260 Rem without having variance. The one thing could be the small Minimize will give you somewhat more h4831sc load data House. Superior luck!gun)
You may have to produce a number of additional posts to receive cleared to try and do PM's. When you finally reach that status I'd put up during the categorised reloading section to determine if any person is near you for any trade.
If you've got some heavier .224" bullets, you may perhaps discover a load that actually works OK Along with the 4831. The bullets I attempted which were above 70 grains would not stabilize in my rifle, which experienced the normal fourteen" twist. The 70-grain Speer was the biggest bullet that might stabilize, but it did that superbly. It is a amusing-seeking bullet that has a rounded nose profile, however it shoots wonderful and kills perfectly. Deer out to about a hundred h4831sc and fifty yards al went down right away with rib-cage hits.
The main reason I switched from IMR 4831 to H4831 was to make the most of the temperature insensitivity of the Hodgdon Intense powder.
Ballistically, this Severe Extruded powder is the precise duplicate of H4831. Bodily, it has a shorter grain dimension, h4831sc load data thus, the designation SC or short Lower. The shorter, additional compact kernels enable the powder to move through the powder steps more smoothly, helping to relieve the consistent slicing of granules.
I have had related knowledge with H4350. For me, some ball powders would not shoot very well with just about anything apart from Fed215's. Some parts just Will not Engage in effectively with other. Seems like you have picked 3 good powders, I'd personally be expecting no less than one of them to shoot.
The "SC" stands for Brief Reduce. I have never seen a difference between either powder dut I do not Assume I might combine them.
I commonly generally receive the sc Model. Utilizing a powder measure it hangs up much less as a result of shorter kernels and I believe enables more consistent metering so less time you are taking trickling in the last little bit of cost to produce bodyweight. So essentially the SC will save you periods
The truth that the H4831 is certainly a slower burning powder is specifically why you are viewing increased velocities obtained with that powder, versus what you've witnessed Together with the IMR stuff.
