I didn't get very good accuracy. I went back to using RL15 and everything was good again. I'm going to try some IMR-4451 which appears to be slightly faster that 4350.

BTW, I use IMR-4451 in a .257 Roberts. Velocities and accuracy are way more than satisfactory.

OK
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.
