Just wanted to take moment and thank everyone on thread for all the great info, especially Mr. Kelley and Tom from MOA. After reading Mr. Kelley's original article when it came out, I decided to take a closer look at the M3000. Hesitated for a while when the issue with threading for the tube reared up. Then reading through this thread I found that MOA had solved this and other upgrade issues, so a couple of weeks ago I pulled the trigger and bought one along with ordering all the parts from MOA. Finally got a chance to shoot it last night. Took it out for some trap (first time in a couple of years) just to make sure it goes bang when expected before I start changing stuff. Sure as heck, it did. No problems with extraction or feeding on any of the shells I tried (Winchester Super Target, Universal, and some of my AA reloads). Strange thing was, even with needing a few shots to figure the difference in aiming point from my Citori, I actually shot better than normal. So now it's on to the upgrades, then more testing and a match at the end of the month. Should all go as well as expected, it will then get a ride to the west coast for the loving touch of MOA.
