My son just got a used Model 10PC in 308. It is a great rifle, but I would like to cut down on the recoil for him. Unfortunately, this an earlier 10PC without the threaded muzzle. So I have a few questions:

I know most gunsmiths want the action removed from the barrel, but are there methods where the muzzle be threaded with the action attached?

I really don't want the accuracy effected, how difficult is this job for a competent smith?

Can anyone recommend a good gunsmith in Northeast Florida?

Any brake recommendations? The rifle will be used primarily for hunting, but maybe for long range shooting in the future.

Thanks in advance.
