    What length and twist rate?

    I found that my 24" 1..9 twist grouped very well with N130 and 40grn anything, but noticeably not as good with N133.

    It shoots 55grn SP very well with N133, but it is a little sensitive to seating depth, and anything over 40 thou back and the groups opened up. Best results were at 15 thou off the lands.
