The 7-08 Ackley is a great cartridge. Expect 3000fps w/140gr bullets and 3200fps w/120's from a 22" tube.
My hunting load is a 140gr AB @ 3030fps, and there is not much it can't do. I've had great luck also with the 140gr NP and 140gr XLC from this rifle... will use the TSX when my AB stash runs dry.
Used this rifle to take Stone's Sheep, Moose, Elk, Black Bear, Mtn Goat, Whitetail Deer and 6yd Grizzly.
Deadly accurate, mild mannered, hard hitting, and feeds flawlessly all in a lightweight package.... what more do you want?
Since I had mine built, my brother and 4 buddies have built lightweight 7-08AI's.... and none have disappointed!
Here are 2 that we've built (bottom one is 6lbs scoped, the other is a hair over 6lbs scoped (my brother's).
