Barrel swap

[Jlbbigbore]

I have a 375 rum in a rem 700 and I want to change my barrel to a 300 rum what is the threads of the barrel and what's compatible

The threads for the new barrel are the same as the threads used for the original Remington barrel. 1-1/16 x 16 tpi. Or 1.062" x 16 tpi. TPI = threads per inch.

Any barrel maker using these dimensions can make a barrel for you. Remember that headspace is an important dimension. If you don't understand this, discuss it with your gunsmith for the sake of safety.

Or get yourself a nutted prefit and spin it on yourself...
