Tango, (shaking head) you can do better than that.
You can shoot whatever grain you'd like from that gun, SAFELY.
However the weight and profile of the bullet dictate what rate of twist will stabilize it best.
1:9 is optimal for 55gr. THe effect of twist on non optimal weights, would not be noticed in ranges of 100 yards or less.
I could make a list of a bunch of guns i have, or "have", or wish I had. Why would one feel compelled to provide that infornation freely? Do you feel the need to show off? Is it some immature game of oneupsmanship?
Why do you feel it necessary to list your guns?
