Win White Box .223 45gr HP powder?

[Ardent]

What powder is Win loading into their white box 45gr HP .223? The closest thing to it in appearance that I'm aware of is 'Lil Gun, but I'm certain it's not, it just happens to look similar. Anyone know or is it a non-cannister powder?

I doubt very seriously that it is anything close to Lil'gun in burning rate.

To duplicate it, either Win748, AA#2015, or AA-2230, or H335 will be really close.

Lil'gun is much faster burning than any I've listed.

NEVER try to identify a powder by how it looks EVER.

steveno, it would seem that the internet is full of your kind. Nothing useful to add, just want to tell people what to do. Now if you know what powder Winchester is using in their .223 45gr HP white box, by all means please share, if not, by all means please keep to yourself

You know he is giving good advice.

first of all Winchester isn't going to tell you what powder they use as it is a commercial grade powder and not a canister grade powder. they have a lab to do their testing in so they really don't need a powder that stays the same from lot to lot. they might not even use the same powder in the next lot. the amount of canister grade powders that are now available to the reloader is the best it has been in 40 years since I started reloading. the testing that the bullet and powder companies have done makes it a pretty safe hobby. I prescribe to the theory that if the powder isn't in a reloading manual I wouldn't touch it with a ten foot pole. if you want to complicate matters by using a commercial grade powder you are on your own

I pulled one and looked at it, weighed the powder charge, based upon my lyman 48 manual, the bullet weight, the powder weight, and its visible characteristics (small grained ball powder) it appears to be Winchester 748. I cant figure out where to get the bullet, one person at my club claims its a sierra bullet, but given the price of a box of these rounds I doubt it.

748 was developed for 5.56/.223 IIRC.

Use published data if you try to duplicate the load.

"...where to get the bullet..." Weigh it and go buy bullets of the same type and weight. However, you cannot tell anything other than the shape and colour of a powder by looking at it.
Listen to Steveno. Ammunition manufacturers do not use the powders available to reloaders. Nor can you buy it anywhere.
