Currently have a savage 6.5 creedmoor and still working off the factory barrel. While I love the gun and the barrel shoots great it isn't threaded and it is still a factory barrel. I am only at about 1400 rounds down the pipe and definitely want to get full life out of the barrel but I am itching for a custom barrel and to try 6mm. If I were to not wait and get a new barrel now, and swap them back and forth would my loads change? I don't want to have to do load development every time i swap the barrel back and forth.
