Here is a new type of fluting one of geniuses came up with.
I built this rifle for one of our wildcats, 30/404. The rifle has a Sako 75 action, and a 27 1/2 Hart barrel.
Several of us used it in Africa last June, using several type of bullets, including Sierra Match Kings, Nosler Ballistic Tip, SWift A-Frame and Trophy Bonded Bear claws. All in 180 grain, with a velocity of between 3430-3480 depending on the make of the bullet.
