    10mm
    1.26\”
    9.5gr Longshot. Worked very well in both 1911 and M&P 2.0.

    9.5 isn\’t over pressure? All load data I find lists 8.5 as max

    @waterman3211 A little late for a reply.

    I worked up to that, with no signs of over pressure. I actually went up to 9.8. Definitely want to hold on. I bought a new chronograph, I\’ll try to post some velocities later this week.

    Hi Bob, did you ever get a chance to put the Longshot and the 180 GR. to the chronograph?
