A calorie is a measure of energy expenditure and stored energy. The calories referred to in diet (calories eaten) and exercise (calories burned) are kilocalories (kcal). One kilocalorie is equal to the amount of heat that will raise the temperature of one kilogram of water by one degree Celsius at sea level.
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.
I drag a bore snake thru it. Same one I use for the M&P 15-22 and my 5.56mm rifles. CLP and a bore snake is all ya need for the barrel of any of these. Methodical cleaning of the barrel is a waste of time as the rifle is just as dirty again after the next few shots.riginally Posted by James7800. I am new to gun ownership and just got my first gun, an m&p 15-22. I have learned a lot from reading the posts around here. One thing I need to learn more about is cleaning it.
