.223 Bullet Weight
My Olympic SUM .223 upper has been doing fine with 55gr ammo but I'm curoius if I can get better accuracy out of a lighter bullet. It's a 20" 1 in 10 twist barrel. I picked up some Fioochi extrema with the 40gr Vmax bullet rated at a crazy 3650fps! I'll give it a shot and see how it shoots.
In general though, what is the range of bullet weights that stabilize in a 1 in 10 barrel?
