Scott78,
Let me clarify my answer a bit. Would I buy a new 40XB? No, I'd have a custom built and probably have it quicker than waiting on Remington. If a tack driver is what you seek and you have the money, build a custom that's built specifically for you. When you get it, Practice, Practice , Practice. When you get to the point that you and the rifle know what each is going to do at all times....Then you'll have a "tack driver".
