I built my ARC primarily to use up the hundreds of custom benchrest bullets and related powders I have accumulated over the years. Bullet weights range from 59 to 68 grains and I have found minute-of-coyote accuracy out of all of them. i really don't feel the ARC case can get these weights of bullets up to enough velocity to worry about over spinning them even with a 7.5 twist.
