Purchased a rifle third hand (owner #2 never fired it) and the thing looks pretty much brand new. It was a custom build from G.A. and I’m finally getting it ready to zero. My question is do I go through the process of scrubbing it after every shot assuming it’s never been broken in or do I just go with it and see how it does? I can try to provide a picture of the bore but as I’m sure you guys know that is a rather futile endeavor. Thanks in advance for any help you offer.
