I have used a ton of it, works very well, accurate and very easy metering.

You need to work up your own load for your particular lot number, but in 7.62 behind a 147 gr bullet I use 45.0 gr.

It's actually much closer to H335. Use H335 data. It's a bit faster (at least what I had) than BLC2.

For feeding a hungry AR, it dosen't get much better. My AR likes the Federal 55gr FMJ over 25.0gr of #WC-846. About 1.5" at 100yds.

According to the burn rate charts BLC2 is one step faster than 846.

Wideners sells military surplus "pull down" powders and this is what Stan Widener has to say about the 846 powder - http://www.wideners.com/itemdetail.cfm?item_id=6673&dir=278|283|999

You must understand that this is surplus powder and not canister powder. Canister powder is consistent from lot to lot as tested by the manufacturer so that loading data will remain constant. So, this means that this powder may vary some from keg to keg as can ALL surplus powder from any dealer and you should be aware of this. ALWAYS START with a reduced amount of powder and work up your loads to the level you want. Check for pressure, velocity, case damage, primer flattening, etc. This powder will probably not vary much, but your results may be very different from mine. That is the nature of surplus powder. You save quite a bit, but you must always approach it with care.

Some people say that blc(2) or H335 is equal but remember these are ONLY guidelines! Work up your own load with this powder that is best for your rifle, your shooting range, your bullet and your special circumstances. You canít get exact loading data so do your own.

When I got 32 pounds of surplus IMR4895, I did not have the knowledge posted above about the difference between canister powder ~ 1% repeatably from reliable sources and bulk powder ~ 10% from surplus sources.

It was a long time before I figured out that it was not acting like IMR4895 described in load books.

If I had life to do over again, I would figure out what I had, early on.

LOT # is everything with surplus powders. Ball C2 is the closest I've found to 846 for .223/5.56 data. Even then, the 10% rule suggested is a very good idea. I tried it otherwise and was experiencing expanded primer pockets with loads that should've been ok....primers falling out, etc. Drop down a few with the lot # I have and everything is ok....groups are sub minute of angle. My RR mid length will print right at one half an inch with that stuff, even with bullets that range as low as 40 grains.

Good stuff, just be aware that LOT # is EVERYTHING with surplus powders!!

I thought WC844 is almost the same as H335 and WC846 is really close to BL-C(2) or W748.

Widners has 844 for ~$10/ pound, which is a great price for a mid speed powder.
