H335 and CFE 223 ?

Does anyone know what the differences are between these two powders as far as fast burning and slow burning, clean burning and accuracy etc ?

There are a lot of "relative burn rate" charts on the Internet. Here is one...

I've used both. I use a bit more CFE223 (26.0gr) to get the same velocity as H335 (25.3gr). Measured over my Prochony Digital chronograph and shot from my SR223E Ruger.

The claims of copper fouling reduction are true.

I don't know, but it may be true that:

1) WW-748 bulk powder is the father of Hodgdon BL-C(2) and Ramshot TAC canister powders.

2) Ramshot has been selling TAC for some time with an anti Copper fouling additive.

H335 is faster than BL-C(2)/TAC / CFE223.

But BL-C(2)/TAC and CFE223 are grouped together in the Hodgdon burn chart.
The word 'forum" does not mean "not criticizing books."
"Ad hominem fallacy" is not the same as point by point criticism of books. If you bought the book, and believe it all, it may FEEL like an ad hominem attack, but you might strive to accept other points of view may exist.
Are we a nation of competing ideas, or a nation of forced conformity of thought?
