I have a quantity of WC 820 and WC 680 surplus powders.

I had seen some comparisions at one time that indicated either a Hodgdon or Accurate powder that were suppose to be the same powder and that loading data could be used with WC powders.

Do any of you know if any of the Hodgdon & Accurate powders are in fact the same as WC 820 or WC 680.

I would like to be able to use these surplus powders in some of my hadngun calibers, 9mm up to 45 Colt.

Call them and ask. They are very helpful. They want you to be safe too. :)

Accurate (http://www.accuratepowder.com/datapowder.htm) even has some data powder data online.

I have a good bit of SRB-118 which is old surplus powder from Accurate. They can still supply limited data for it. I also have an 8 Lb jug of 2230-S.

WC 680 and AA1680 are near identical. I use both in my 7.62x39 on a regular basis. I called AA for this info.

WC680 was identical to Winchester canister grade 680 that was discontinued over 20 years ago. AA1680 is what works for WC680 today, but, work up cautiously

WC-820 is M-1 carbine pull-down powder. The first bunch of that # that showed up could be loaded like ww-296 or H-110. But the latest WC-820 that's around now is more like accurate #7, much faster than 296 or H-110. It works well in magnum handgun cartridges, use #7 data and work up.

I'm using it in 7.62X25 shells, it makes a colorful fireball but is nice and accurate.

Lately, the surplus powders are almost EQUAL to canister-grade brand name propellants in price, but NOT in availability.

Other than a few odd pistol powders and stuff suitable for not much more than .50 BMG, I haven't seen a good deal on surplus powder for almost a year.

Off-topic, but I *had* to say it.

I have been using surplus bulk military powder for years.
You can read the brass bulge or primer pierce in 9mm work up and adjust.
You must be more careful in 45Colt, where some cylinders might split before the brass got sticky.

I got 32 pounds of bulk IMR4895.
The results did not match canister IMR4895, it was faster.
I use Quickload software.
The surplus is an exact fit for H322 Quickload predictions for pressure and velocity.
It is not a fit for density.
It is a perfect fit for IMR4895 for grain stick diameter and length.

Here's what's on Jeff Bartlett's website as for powder right now. The ONLY one that's usable for most rifles is the 4895 stuff. I got some of that, but over a year ago, it's right on for use with IMR-4895 data.

WC872 Original application is U.S. 20mm Vulcan ammo. A ball powder which
can be loaded using Hodgdon H870 or AA8700 data.
This is pulldown ball powder.
$56/8# jug.

WC860 Original application is U.S. .50 Cal. BMG ammo, used for the Ball
M33 and API M8 projectile. A ball powder which can be loaded using
Hodgdon H870 or AA8700 data.
This is pulldown ball powder.
$56/8# jug.

IMR7383 This is a slow burning stick powder originally used for the Cal. .50
Spotter/Tracer round. It has a burning rate similar to IMR4831, but
is much more bulky. It can be loaded using IMR4831 data, but by same
volume, not by weight.
This is new powder, not pulldown.
$70/7# jug.

4895 Ideal powder for any .30-06 Cal. Ball M2, AP M2, Tracer M25, or
Match M72 milspec ammo. Considered to be a "one size fits all" type
powder that has loading data for most all cartridges. Testing has
proven this powder very accurate. However, this lot burns slightly
slower than IMR4895, closer to IMR4064, but is bulkier.
This is new powder, not pulldown.
HAZMAT fee waived on 6-jug orders.
$100/8# jug.

The gurus on this subject live over on http://castboolits.gunloads.com/forumdisplay.php?f=28 WC820 varies by lot number, and there are a few of them. As others pointed out, it used to be like H110, but I have a lot that's like AA#9, which is good news indeed.
