I guess I don't understand. Several people with experience, some with much more than I have, have advised spot annealing, which works for both drilling and tapping with standard tools. Yet, some folks have simply ignored that suggestion and keep hoping for some magic drills and taps that will cut through that tough steel Remington used.
Spot annealing (about 1/4 inch diameter) will do no harm, will not weaken the receiver, and any discoloration will be covered by the scope bases. Pardon me, but I don't see the down side.
