A twist faster than 1:9" is better than stabilizing the heavier bullets commonly used in highpower. A 9 twist will stabilize bullets to 68-69 gr, and MAYBE as heavy as 75-77, but do not count on it. For reduced range (to 100 or 200 or 300, not 600 yds), the lighter bullets are fine. Lots to learn even at reduced distance.

A 1:8" twist will stabilize the 75-77 bullets, so a 7 twist is not "necessary".
