Got a a CZ550 in 416 Rigby and really like the rifle and quality, but the twist is 1:16.5. I have run the numbers and according to length, it should barely stabilize the 400 TSX I am shooting. I don't want the bullet to drift off in some wierd direction on impact because of minimal stabilization. Just bought some 400 grain Partitions and 410 Woodleigh solids to try, which should stabilize well.
For those who have shot game with this caliber, what would you use?
A 1 in 12 would be perfect for the 400 grain TSX as well as any other bullet. A marginally stabile bullet can do squirrelly things at impact sometimes. The 350 TSX would work well with your present twist rate.
