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.

Greetings Zimmer,
The thing that made me distrust the NH loads was the .223 loads for AR2206. A spanking new Rem 700 VSSF in .223 had found its way to my house in 2005. I had been loading 26 grains of AR2206 behind the 52 and 55 grain projectiles and getting close to 3,300 fps in my old Brno with a well used leade. My recently aquired NH manual gave a max of 24.5 grains of AR2206 for 3,300 fps. Cautiously some loads with 23 grains were assembled. According to NH these should have given around 3,100 fps but chronographed 2,900 fps in a 26 inch barrel! A bit of digging found an older ADI pamphlet that gave a max of 25.5 grains of AR2206 for 3,260 fps which is what I got a bit later. More digging found that Nick had just copied the old AR2201 data from his 1980 version and failed to update to the later ADI data. Had I not had a chronograph I would not have spotted it.
Regards Grandpamac.

I have NH 3rd....nosler 2nd and 4th? a sierra and about 10 wee paper ones including ADI vitavouri and winchester.....really old mulwex one is gold.... and check online too.....call me anul but like 3 sources of info to roughly tell me same thing before will load case....
