AA#7: It was originally developed for this application with heavy bullets.

HS-6 another good powder for this as well a Longshot and Sillhouette.

You want / need a powder with a longer recoil impulse to move that heavy blow back bolt design with enough energy and pulse duration.

TG and BE are a bit on the fast side for this application. It's not that they can't be made to work but they don't work well.
