It was very odd! Only time I've ever seen a bullet deflect like that myself.

The twist rate that I will be using is 1:8" with 3 grooves instead of the standard six to releive some of the stress. You need that fast of a twist to stabilize 160 gr. bullets in a .264" bore (a smaller bore requires more spin to stabilize a bullet of a given sectional density). After I am done experimenting with extreme velocity, I will move to what I designed this rifle to shoot: 140-160 gr. bullets. They drift less in the wind and I feel more comfortable with the greater mass.

The .257 STW is a mighty fine cartridge, I can see why your uncle wants one. I thought that at least one manufacturer had started selling guns already so chambered, but I'm not sure. The only reason why I went the .264 route instead of the .257 route is that for some or another, bullet manufacturers don't make anything over 120 gr. for .257's, yet .264's go up to 160 gr. so I felt that the .264 was a little more versatile.
