Back in the 70s and 80s it was known that there were (at least) 3 DIFFERENT burn rates identified in H110 canister powder. I understand H110 is much more consistent these days, but EVERY powder has an allowable variation in burn rate from lot to lot.

I only see a problem if you consider someone else's data to be absolutes. I don't, simply because there are too many different factors at work between what they tested and what I have.

Guidelines, not absolutes...
