View Full Version : WCC 846 or 844 for 7.62 & 5.56

December 18, 2006, 01:42
Now that there is some WCC 846 available, I'm going to order some. I'll probably order 4 - 8lb. jugs. My question is since I load for 5.56x45 also, should I get some WCC 844 instead of all 846? I've mostly used surplus ammo for my STG 58. I've loaded some 7.62x51 with 748, BL-C2, and 4895. I know 846 is basicly BL-C2. I reload almost all my mouse gun ammo. It really irritates me to pay more for 5.56 than for 7.62. But it appears, those days are gone for now. So I'm going to save my supplus and reload for both. In 5.56, I've used H-335, AA 2230, BL-C2, and Varget. I load 55 gr. bullets in the 5.56 and 147-150 gr. bullets in the 7.62. So, would you keep one powder for both or do you think having the slightly faster burn rate for the 5.56 is worth having two powders?

I have used WC844 in both 223 and 308. I find it works great in 308 for mid weight bullets and functions well in both AR10s and 1919A4 belt fed. The only time I found WC846 to be better was loading 155 Amax bullets. With WC844 I could not get to a reasonable velocity without high pressure signs, WC846 I get 2650 F/s from my 20in AR10, good groups and no high pressure signs.

Who is selling it cheap?

http://www.patsreloading.com/patsrel/prices.htm has it for $80/8lbs if you buy 32lbs. They allow you to mix and match with their various powders.

I have been loading with 844 for both, but the BBT has 32 lbs of 846 and 16 lbs of 844 on the way.

I'm curious to see if the jugs have any loading data like my previous order of 844 had.

There are some pretty good discrepencies in the BL-C(2) load data.

Thanks for the replies.

"There are some pretty good discrepencies in the BL-C(2) load data."

Bob, after reading your post I dug through some of my loading manuals and have to agree. Especially, in .308. Speer numbers 10 through 13 list 44.0 grs. max. Yet most others I have go from 47.0 (Water's Pet Loads) to 49.0 (Lyman #47). The .223 doesn't seem as bad (25.0 to 27.5). Although statisticly they're about the same.

I'm tempted to just order 846 as it's burning rate is a little more versatile for other cartridges I load for. I found data for BL-C(2) in .22-.250, .257 Robts., .300 Sav., .32 Win. Spl., .35 Rem., and .45-70. Other than the Hodgdon data, most of my sources didn't use H-335 (844) nearly as often as BL-C(2) in those cartridges.

Maybe I'll get some more responses, particularly about 846.

Ok the BBT got here.

Here are the labels:

WC 846 - This powder has a burning rate like BLC-2 powder. Work up all loading data by reducing BLC-2 starting data by 10%. Customer assumes all responsibility blah - blah -blah.

Starting load for 308 Win. using 147 FMJ bullet is 40.5 grains.

WC 844 - This powder has a burning rate like H335 powder. Work up all loading data using H335 starting data. Watch for pressure signs. Customer ...

Starting load for 223 Win using 55 FMJ Bullet is 24 grains.

Thats the same starting load as the Speer Manual and higher than Lyman 47 at 23 and the Hodgden site at 22.8, so I think its safe to continue using my current load of 25 gr for 62 gr M855.

The 846 goes back to the discrepencies in the various manuals for the Bl-C(2).

The military loads it at 46 gr. Lyman has a maximum of 49 and the Hodgden site 48 gr. Speers maximum is 44 which is lower than the starting loads at the other sites.

So, any opinions?

I've loaded 46gr of BL-C(2) in commercial brass with no high pressure signs.

Magnum rifle primers
150gr M2 pulls

Average velocities @ 25 yards from muzzle
Winchester brass: 2477
R-P brass: 2570

I would imagine that 147gr M80 bullets would be a bit faster.

I plan to work up loads that are closer to 2750. I have a feeling those will be in the 47-48gr range.

Nice info guys, thanks. I picked up some 846 from Pats myself and haven't used any surplus powder before. Most of mine will be in mil 223 and 308 brass.

Make sure you shake the powder up before you reload with it.
