My question is, just what depth do you drill the receiver at. Is there a certain recommend depth you want to go?
Any advice would be great.
Normally the scope base screw holes are through drilled With the barrel off on the front receiver
ring and the same on the back.(It is easier to tap all the way through)
They must be cleaned up on the inside of the action very well.
Then the screws must be fitted not to go all the way through to the inside.
The screws should have a minimum of 5 threads of engagement.
If you don't remove the barrel the front screw hole will have to be blind drilled. (Don't drill into
the barrel tenon).
