Could anyone tell me what the correct twist is for a 7 x 57.


Never rode a bull, but have shot some.

7X57 rate of twist is usually 9 in 1.

Politicians should wear Nascar Driver's jump suites so we can tell who their corporate sponsers are!

Rick, LOL, you caught it too. We know he meant 1 in 9.
Theoretically a bullet exiting a 9 in 1 bore at 2500 fps would be doing 16,200,000 rpm.
