When a pound....isn't a pound.

It's my understanding that some powders cost more to produce... W231 is an example.

It's interesting, talking about cost and price points. There are quite a few powders out there that are generally available, like Accurate and Ramshot, let alone powders like Shooters World and other knockoff powders... that cost less but do what more expensive powders do. Why isn't everyone buying those... assuming overall price is such a consideration?

To some extent it's load data. Ramshot has no data for .32S&W/H&R or .38S&W in their listings - among others I load for quite a lot..
