I cannot imagine Bore Butter for a wood stock... I understand it is just soft wax in a food grade oil base. And it is sticky enough to collect dirt without hardening. I would be shocked if Cooper actually suggests it.
It is like Pledge and other such crap that looks fine with minimal effort, but needs to be done again very soon after. The waxes they use are soft...
Curious enough was I so I called Cooper... Yes, they did recommend BB on Coopers "many" years ago. They have some BP shooters there that had made the suggestion. They now suggest a commercial "Wood Cleanse" product.
The fellow I spoke to emphasized their finish does not in any way seal the wood and a paste wax base coat is what they believe in on their finished stocks.
