I'd be interested in that data from the Handloader newsletter.

I hope that anyone who reloads knows that older data is only relevant to powder manufactured in that particular time frame (and it should be dated). The chemical composition changes without notice from the manufacturer and the burning rates, charges, even physical appearance change as well. Older data may no longer be correct.

Even loading data for the two most common powders, Bullseye & Unique, have changed over the years.

I would caution anyone using the data in any of the articles in this thread or the other one view it with skepticism.

I plan on using only the lower [minimum] loads and then only one or two rounds, to get a feel for how they shoot.
