How do I keep the front screw on this scope mount from backing out?
I sighted my new S/A NM in w/Federal GM 168 BTHP’s.Shot 5 in a 1/2” group @ 100yds.This was after firing approx 6 rnds to get it in the Xring.
Luckily my first round-(no bore sighting) was @ 10 o’clock in the 9 ring.
Took it out...
