I picked up a 50ct. box of one hundred sixty Nosler Accubonds, but I'm hesitant to burn up the powder and projectiles on workup when all I have is 50 bullets. But I really need to locate a bullet while in the one hundred sixty class that my older rifle likes.
H4831SC Powder accessible in stock now. Ballistically, this Excessive Extruded powder is the exact copy of H4831. Bodily, it's a shorter grain dimension, for that reason, the designation SC or small Slice. The shorter, additional compact kernels allow the powder to move in the powder actions extra efficiently, helping to alleviate the constant slicing of granules.
The obvious lead to is a rough/ruff bore. No degree of copper fouling lowering brokers in the powder will right this.
243, and a number of the loads I've begun with consist of, you guessed it, H-4831sc. This time I'm about to shoot the IMR7828 loads initially, accompanied by the W780 loads just so there won't be any surprises in the event the H-4831sc loads exhibit a shotgun pattern! Who is aware, I just could discover a use for it after all.
My practical experience is that the SC and SSC loaded to the exact same excess weight given that the extended Reduce demonstrates a lowered velocity.
Did you ever test H4831sc in you 300wsm and 215 bergers. I've a 300wsm now. Shooting 180g with H4350 at 2940fps with normal chamber. Wanting to know What to anticipate with 215 bergers with H4331sc?
Nampa, Idaho In my encounter the sole serious difference is that the shortcut meters greater through reloading devices. As soon as It can be loaded theres no useful distinction. I've heard which the shortcut might have a tiny little bit more rapidly burn charge but it seems insignificant.
and you might want to invest in some new load data guides. powder composition and chemistry can does transform over time. 4831 powder of decades in the past isn't really exact same as what's now available. that is definitely why someone seriously interested in reloading safely and securely should have probably the most present load data publications to seek advice from.
Any load data to support that? My first assumed is it's actually not about to burn up each of the way and velocities will probably be sluggish and all over. Could be a nice fireworks Display screen!

It has been a little bit, but I did get some 4831 SC to try. Discovered a node and shot some groups. I shot a .6 5 shot team now. It is really a little bit slower than H1000, but shoots good. Many thanks for the recommendation, It truly is very good to are h4831sc aware that I've received choices when 1 or the other powder is dried up.

Naturally, sitting about h4831sc load data for twenty+ decades (I am aware a man who continues to be using the H4831 he acquired while in the 60s), implies that burn fees will most likely modify a smidge, and new manufacture stuff will likely be a little distinct as well.
