At 7 WSM/ SAUM/ Phagnum velocities I haven't had any trouble stabilizing the 180s..... ala 9-9 1/4 twists...
No joy in a 8 1/2 Rock tubed 7/08. If'n I'm building a 7mm from scratch these days, it wouldn't be any slower than an 8 twist.
I agree with Stick though... Just send me that turd and buy yourself a Vudoo...grin...
