RE: Point of concern?
While I don't dispute your findings in regards to Hoppies, I must tell you I have never used justwater in this rifle (3+ years) and have never had a rust problem. I do use water on my sidelocks since it is so easy to remove the barrel and put it in a bucket. The brake cleaner will take outanything the Hoppies leaves behind. The only thing that was different this time was the use of BM3. The gun has sat at times up to 3 or 4 months between shooting sessions with no hint of rust. This time it had only been 2 weeks.
I have been considering getting some of the BC Sheath as I hear good things about it, plus I'm getting low on CLP and may switch to the Sheath and try it out.
Thanks for all the comments and words of wisdom and I hope everyone gets a shot at whatever you are hunting this season. Good luck and good shooting.
