First DM is very picky about his drilling and I dont believe he would have just any drilling smith work on this drilling. I understand there are 5-6 drilling smiths in the USA.
JJ is working on 2 of my drillings, opening the chokes, expanding the shotgun chambers for 2 3/4 inch shells and putting on scopes.
Interestingly my scope choices have been limited to the location of the claw bases. Having said that, what is the rifle caliber and what power is the scope is on it now?
