Thread: Best adi powder data

Just further echoing Grandpamac's views. I wouldn't trust any of the data in Harvey's book, unless you can corroborate it against modern reloading tables from the main players.
As pointed out, virtually all the loads are copies (stolen) from other sources ie not Harvey's personally tested loads. Although he did do a reasonable job of load development for various pet calibres which were then published in the magazines he used to write for.

I have I think his first edition. In it there are several load corrections done by sticking in bits of paper. This is as bought. Not too inspiring.

The 110 grain load with 2208 when checked roughly in Quickload (keeping in mind QL is a guide only) suggests that at the 45 grain load of 2208 around 15% of the charge is not burned in the barrel.
The predicted velocity for the 45 gr load falls short by 200 fps from that in the book. I used 110 gr Speer, commonly used back then, as a projectile. Other brands/types of profile may show better performance.

On a brighter note, it is unlikely that pressure would be an issue.
