I have had bases come loose before and when a 0.25" rifle starts printing 2" suddenly............. it's scary!
Diagnosis was expensive, time consuming and really inconveniently timed. Ammo was waisted trying to figure out if it was scope, base, rings, ammo or barrel.
Now, every scope base I install gets bedded. Or rather bonded...........It's like bedding but without that pesky release agent. Never a hitch since :)
