Anyone use it? I know its comparable to Winchester 748. I am especially interested in using it for .223/5.56 with Nosler/Sierra 77 grain hpbt? It only comes in 8 pound jugs so I'd like some reviews before I buy so much.

I got a jug of it a while ago and have loaded up some 308 with it.  I used BLC2 data to load it.  I found it to be quite accurate.  I plan on loading up some .223 next chance I get to get to the range.

I went through 8lbs in 55gr plinking loads. I can't speak to the accuracy, as the bullets were pretty much garbage pulls. I just used it for guilt free blasting. Burned good though, and it was cheap.

That said, I've got some chrono data for 24gr of 846 under a 55gr from a 16" and an 11.5" gun if you needed it for some reason.

Huh???

It's usually said (for data use)........

WC844 = H335

WC846 = BLC-2

I'm NOT saying that it's an exact/direct replacement. So, of course...........start low and work your way up. Take all standard precautions when approaching any "new" load.

And, YMWV.

I had some left over 748 laying around so I loaded up some Nosler 77s to see how the heavy weights will fare with that burn rate.

Is 846 a ball powder? I use a Hornady LnL AP so if it flows through their powder measure well that'd be a bonus.

    I prefer 4895 surplus , if it can be found .

    I am not greatly impressed with WC846 , I found it gets touchy with 168 grain bllets in 7.62 NATO , when you get close to max .

    Loaded some in .223 , but it did not seem as accurate as AA 2200 .

God bless

Actually the guy I got my powder from sold it as W748 but once I got it and started looking in to it I saw that it was actually BLC2.  Looking at the loading data 748 and BLC2 are about the same but the BLC2 was normally a lower charge so I used that data.

WC 844 was actually taken from one end of the WC 846 production as lots on the extreme end of the burn rate range for WC846 were found to be more suitable for 5.56mm M193 production - so it got it's own specification.

The thing to remember is that canister powders (BLC-2, H335) are designed for a degree of lot to lot consistency that does not exist when you talk about WC 844 and WC 846 from different lots.  Ball powders in general are made in large lots and then different lots with different burn characteristics are then blended to get the desired burn traits.  Those large lots meeting that specification are then used to develop the specific charge weight used for that really large lot.  And the charge weight for a given application will vary from one lot to another.

In short you'll find a lot more variation from lot to lot in a powder intended for large scale ammo manufacture than you will find in canister powder.

Unfortunately now and then someone pulls down a single round or a sample from a single lot and then definitely states that a certain mil-spec load uses x grains of x powder when that is the case only with that particular lot and the same charge my be either in insufficient or a dangerous excess charge with another lot.  So start low and work your way up slowly.

As for the story of WC844 and WC846........

OK... So what about this?

It's commonly understood that BL-C(2) is fairly temperature sensitive as far as powders go.... How is H335 in this regard?

I was thinking about grabbing some as it's a little faster burning (so might be a better choice for a 16" barrelled 7.62) and I like in a place where the weather can go from 20 degrees in the winter to well over 100 in the summer.
