What's Wrong with SW Match Rifle Powder?

[LRRPF52]

I?ve done searches here and on google, neither turned up very much.

I?ve seen our fearless leader BFT say Bill Alexander told him that A2520 was the best all around, perfect Grendel powder.

The Western Data book shows it as the fastest powder in all the lower Grendel weights. And from what I can find, the Shooters World Match Rifle is ?exactly? the old tried and true A2520 formula!

So what gives, why so little data with it? Is it wildly temperature sensitive? Can?t be any worse the CFE223, which is about as close to the same burn rate, without actually being a clone.

Where?s the love?

Edited: It’s getting old having the apostrophes and quotation marks replaced with “?” In my posts. What gives, how can I correct this?

AA2520 has been one of the most common, most popular powders for 6.5 Grendel from the start, with a ton of data on it.

It was one of the most common powders in the original Alexander Arms published data, Accurate Powders data, Hornady data, and data in the 6.5 Grendel Handbooks especially for 120-130gr cup and core bullets.

It's also one of the common ball powders for .223 Rem, .243 Winchester, and .308 Winchester.
