Can't help you with those projies but the only adi powder I've had top results with is 2208 - 70gns behind the Woodleigh 270 PP. av.vel.is 2655fps and 18mm groups at 100mtrs. played around with 2209 (80gn) but never got good accuracy always around the 50mm mark,av.vel. 2685fps
Bakes has mentioned some loads from Nick's manual and on the whole he's pretty well spot on but I've found some weird loads in there ie:

Nick's loads for 270gn projie

ar2208 68.5 to 74 max
ar2209 74 to 78 max

ADI manual

ad2208 67 max.
ad2209 83c max.

Big difference as you can see?? 83gns of 2209 and 74gn of 2208 is way over the top in my firearm and 67gn of 2208 way too low. as is the 78gn of 2209 load. like to know how ADI done there testing.....Les
