Lyman book powder types question

[SanDiego619]

Hello, I have the Lyman 50th edition and I have a question about powder names.

For 223 for example there are things listed like IMR-4198 or Varget. Those I can find. But there are others like "2015" or "2230" or "2460"

What brand are those? Are they just so well known in the reloading world that they don't have to put the manufacturer? When I google it seems like all of the above are Accurate by Hodgdon, is that correct? Some of it is actually in stock too...

Yes indeed

Just be careful of powders like 4198...you have IMR4198 and H4198. They are 2 different powder.

I noticed that today, why would they choose the same number as IMR when the loading formula is not the same?

At first, I assumed they just changed the name but the powders were the same... then I learned that it was a different product. It seems funny to keep the name like 4064 but it's a different powder.

I hear ya man...

Look a Winchester 231 and Hodgdon H-38. They claim to be the same powder. I don't know if they're the same but they do produce the same results

There are powder classes like 4350. Although several will call theirs by the same numbers, they usually are not exactly the same. They may have similar burn characteristics, but they are not the same. Thinking you can just inter-change them could yield deadly results.

Sierra 50th Anniversary Manual lists powder "AA-2230'' for the .223 Rifle Cartridge
ranging bullets weights from 55 grain to 69 grain.

I don't know if your 2230 powder is the same as Sierra's AA-2230.

I do know that in the mid 1980s there were plenty of USPSA AR competitors reloading 223s with
55 grain fmj bullets . The powder they used was 2230. But I do not recall any other 2230 rifle
powder identifiers. During these times 2230 powder was inexpensive & plentiful.

They are accurate powders.
Yes, they are so well known that you don't need to put the AA in front of the number like some reloading manuals do.

IMR came first.
Hodgdon came later and markets different powders that perform similar to the IMR versions, but the powders being different means that the load data is NOT interchangeable.
Hodgdon does not actually MAKE any powders.
They buy powder from powder makers and package it for sale to reloaders.
