I'm looking for a good gunsmith in the NJ/NY/PA area to swap a 7mm Rem Mag barrel for 416 Taylor on a Browning Safri Grade Rifle. Any suggestions?

Bob White in Lake Hopatcong, NJ - while he's more of a Benchrest/Varmint gunsmith, but fitting and chambering a barrel isn't going to be a problem.

Nice guy to talk to, and you'll spend hours in his shop looking at all the rifles he's got in his inventory.
