To answer your question directly. When a customer reloads and still gets bad results the rifle comes back to me for full inspection, accuracy testing, and full warranty re-barrel if needed.
But if a customer says.......I bought tons of remington core-lokts (or any other factory ammo) and the rifle doesn't shoot to the accuracy guarantee.....it needs rebarreled until the stars align and shoots them to guarantee......sorry not happening. If this is the expectation from the customer they need to mention it up front so costs can be added, some other arrangement made, or the build turned down altogether.
You either trust your builder to do a quality job to the best of their abilities or you don't.
If my responses leave a bad taste in your mouth, I understand. There are plenty of other great builders out there.
My apologies for hijacking this thread, but I am glad it went down this path. I would rather be honest and possibly lose some future customers, than promise the world then "read the fine print" you later on.......all to common in this industry already.
Also, I speak for myself alone, not anyone I contract for. Their arrangement with the customer is not my business.
