Break-In Procedures: 1  Clean barrel after each 3 shot group for the first 60 shots or more if needed. 2  Check to see if there is any visible copper fouling. 3  Take one of the clean dry bore snakes, soak with copper solvent, and run it through the rifle from chamber to muzzle 3 times and let sit for about 10 minutes.
If you intend to use rainwater for drinking, minimizing contamination is essential. Keep the rain barrel clean; remove overhanging branches and any debris on roofs or gutters.Use fine wire mesh to keep leaves, bugs and other materials from getting into the rain barrel.he rain that falls in cities or flows across outdoor basins, roofs and other open air surfaces on its way to a barrel is another story. Contamination from animal feces, dead insects, engine oil, car exhaust, lead paint and other substances can make drinking it a health hazard. (See References 1, pages 120e and f).
