After reading through this thread again, another thought came to mind. Blank "ammo" is loaded for many different calibers. The military loaded .30-06 blanks used a powder known as...

WC Blank was used to load U.S. Military .30-06 Blank "ammo". It is a VERY fast burning powder. Under no circumstances can this powder be used in any cartridge as a propellant charge for a...

RVO-65 is military surplus WC-860, used for .50BMG ammunition.

This "touch of red dust" you describe is an early indication of propellant break down as the stabilizers begin to deteriorate. This makes the powder unstable and unpredictable. Remember, that in...

RVO-62 was surplus WC872

UPS will not ship gunpowder to HI or AK, nor any of the territories. All UPS shipments to these destinations require some air transportation, and they will not knowingly accept this commodity.

BCB - I think you have a "bad" lot of WC872. Is your lot from pulldown? If you like WC872, I'd try a different lot number, or perhaps try WC870 or WC860. All of these have very similar burn rates....

I had a similar issue with some WC860 powder. This powder was indicated as pulldown, and not new. My conclusion was that during the demil process, the powder probably had been exposed to high...

If this powder is indeed WC820, and lot number unknown, use Accurate Arms #9 data. Begin with starting loads, and work from there.

The military has sourced "WC" type (double-based, spherical) propellants from at least 2 manufacturing plants (Badger and St. Marks, come to mind). Manufacturing procedures could have varied, which...

Win785 is (was) a very slow burning ball powder, similar to Hodgdon H450 or Accurate 2700. The military version is known as WC852 (waviered, ie slow). It burns too slow to be compatiable with the...

According to my records, there are three (3) lot numbers of IMR7383 floating around. One lot was made by Radford, lot Rad78L- 47985, and two (2) lots by duPont, lot #48000, and 48001. The Radford...

My experience with IMR7383 indicates this powder is about as slow as IMR4831, as Jeff Bartlett indicates. Loaded in .308, 40 grains filled the case almost to top of neck. Velocity with a 147gr M80...

Hodgdon sold powder in those "coffee" bags thru the 1960's. H-380 began as surplus WC852, which the military used in .30-06 only. Hodgdon also had H-375 which appeared before H-380, and was...

When Accurate 2520 was first offered, it was nothing more than surplus military WC852. This lot had a burning rate similar to Hodgdon H380 or Win 760. All of these started out as surplus WC852. ...

I've worked with three different lot numbers of IMR7383. Two were from duPont (48000 and 48001), and one from Radford. The Radford lot was Rad78L47985. The Radford lot was the fastest, then duPont...

During WWII, all .30-06 military ammo was loaded with the IMR4895 type powder. WC852 was loaded only by WCC, and I have not found any WCC ammo headstamped during the war years (1941-45) loaded with...

The powder is definitely WC852. This ammo...

Larry:
After re-reading your last post (#14), I notice you mentioned some LC69 Ball M2 with a charge weight of 44.5gr of IMR4895. I suspect the powder is not IMR4895, but actually CMR100. If you...

Larry:
The "Alternative" loading was the beginning of the GMCS (gilding metal clad steel) projectiles. The clad steel reduced the amount of gilding metal needed, and made the GM material last...

The powder is definitely WC852. This ammo should exhibit evidence of once being linked. This will prove that the ammo left Lake City in MLBs (metallic linked belts), and was expected to have been...
