Re: brand/length/twist opinion
It is going to depend on what diameter shoulder the original barrel had. Savage has a 1.050 thread OD + the diameter of the nut. The Remington tenon is 1.062x16tpi in addition to which it has a shoulder. If you measure the base of your Remington barrel and then compare that dimension to the OD of a Savage nut, you will know if any inletting is needed. Typical Remington contours have a 1.2" or 1.25" barrel shank diameter and for either of those one should be very close indeed to the diameter of the barrel nut.
