No, but I think a good test for you would be next time you shoot, clean with clp as you normally do. Then next day sop the bore with hoppes and let it sit 15 min. I think you will find there is a ton of black crap that will come out. I did this and now use clp for quicky cleaning, but hoppes if I'm serious about a deep cleanHave been using a CLP (FP10) since it was deemed the " preferred" product for cleaning the issued weapon. Before that I used Breakfree on everything (also a CLP). I guess what I'm saying is, I have never used one product to clean, and one to lubricate and protect....do I need to rethink my post-range protocol?
