here's one for ya- I built a halibut rifle about 20 yers ago- .223AI on a 700, Rock 1-8" #2 @22", sitting in a classic. I put a shim in the back of the mag box. The bottom of the bolt sort of grabs the follower and drives it forward. It looks to me like the .223 follower is too sloppy front to back, now that the oem spacer has been replaced by a smaller one. Is there a fix for this, besides M5 dbm?
