48.5gr of H4350 under a 140 Accubond going 2875fps from a 20" barrel.
Also have a 120 TTSX over 42.5gr of H4895 for 3020fps.
My 7-08 Ackley isn't any faster than a standard 7-08 that has a 22" barrel...
Long brass life and no trimming is nice. I'm getting 12 plus reloads before the primer pockets loosen up.
Two of my buddies have 22" barrel 7-08 Ackleys that get 3000fps with 140's using 50gr of H4350, but that load is too hot in my rifle, stiff bolt lift.
