+1 on 44.5grn of N140 behind a 155 SMK (2155 or 2156) or Lapua bullet head. Use this in a few rifles, (I always full length size cases)
20inch Remington 700 gives 2666fps
26inch Remington 700 gives 2780fps
30inch Barnard P action with true flite barrel gives 2950fps
This isn't really a hot load and would probably be fine in your AI AT but ALWAYS start lower say 42.5grn and work up.
I haven't shot any GGG ammo but might pick some up to try.
Good luck and please post pics of how you get on.

Amir would like to point out that the word for the concept of "englishcentric" in the language of the English themselves is "anglocentric".
Amir is greatly amused and much pleased at this opportunity.
