Had a cutting board on standby, but I guess I'll just put it back in the cupboard. The dog and I just freehanded them about a half hour ago. Mounted the mojos for a 315, 9mm rear of center. Plenty o meat to drill into, "mount anything" plates not really necessary for this application. Just hope this is a help to all those who got in on the group buy and the SAC deal the other day.
