Have my eye on a high grade 99 chambered in 22 High Power.

It has a dark bore and may need to be rebored.

There may not be enough "meat" to go 25-35 the first choice.

That leaves 7-30 Waters or 30-30.

Question is: Will the HP rotor work with 7-30 Waters or 30-30.

Same basic case but quite different shape.
