Simple ... I don't use BB anymore. I found (for my liking) that is barely adequate as a ...
* Protectant - There are much to significantly better products. Like Ballistol all-around or just in the bore and Birchwood Casey's 'Barrier Protect' or 'Sheath' product (same item, new/old names) for externals.
* Lube - It's plain terrible in the ccccold. I was shootin in -1-degree F conditions the other weekend in VT and TOW's mink oil stayed viscous. In fact, I saw no less than 6 rammrods broken using BB in about 2-hours of duty as a range officer at a shooting station.
* Seasoning agent - In fact, I feel that whole premise is hooey! I have also witnessed firsthand that too much BB build-up WILL destroy your groups.
That said, I know many that use it within their context and are happy with it. So the real lesson is ... your mileage may vary. Good luck! And always make it fun :thumbsup: !
