Think there was one Q that wasnt asked here, was 3" done off hand or off the bench?
From the bench Id agree with everything suggested as you should really be getting a 5 shot cloverleaf at 50 yds with everything done up right off the bench.

Now iffen yer getting 3" offhand well, a silver star goes to the shootist. I reserve gold ones fer those that can do 3" offhand at 100...
