150 Remington SP on top of 47.8 gr of IMR 4320 a shade under 2800 fps
Winchester primer, everything is stuffed in a Military surplus case or some Remington & Winchester brass, I'm not going to use some fancy brass in a weapon notoriously hard on Brass I save that for the bolt guns.
I don't know what to tell you about accuracy, I can consistently hit a 10" plate at 400 yards plenty good enough for poking holes in predators. I don't shoot from a bench with any of my AR's that's not the intended purpose of the AR's IMO. Multiple targets running like Hell after the first shot is where they excel.
I like the 150's and have played a little with 168 & 180 gr bullets but again, I like the performance of the 150's its NOT a round that I would use if I'm pelt hunting its really chews up hide. I use the 308 around the house to get rid of predators that's its main purpose in life.
a little off subject
Penny & I go Pelt hunting she carries an AR in 223 and a Rem 700 that was originally a Varmint Special in 223 when the barrel was shot out it was made into a 20 Practical an excellent Pelt Hunting round.
I carry a AR in 223 & a Rem 700 in 243 for larger predators or when they think they are out of range and laughing at me.
all of the bolt guns wear Lilja barrels from Plains MT & I use a Gunsmith that's the Yoda for Gunsmiths IMO
Happy Shooting
