American 300 BLK

[22/45 Fan]

1 in 7 is an awfully-fast twist rate for such a slow-moving .30 Cal bullet. Actualy, it's an awfully-fast twist for ANY .30 Cal rifle.

The stability any bullet depends on its rotational speed and length. For a given bullet the slower the muzzle velocity (and the slower the rotation speed as a result) the faster the twist needed to stabilize it.

The 300BO was designed to shoot long, heavy .30 caliber bullets at subsonic velocities so a very fast twist is required. For normal bullets at higher muzzle velocities, the fast twist isn't required but, unless extreme, doesn't do any harm either.

Well he has one,short compact and I think that would be best for the grandson. The trigger was light and clean with no creep but he also has a sp101 WC so I got that instead, oh well. I'm gonna keep watch for reviews and get one the first of the year,now that they are out I was told should be able to get one easy.
