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.
If not, use a muzzle guard. The muzzle guard keeps the cleaning rod from banging against the muzzle, which can cause your gun to malfunction. 1  To thoroughly clean the barrel out, push a solvent-soaked patch through the bore until it exits the other end. 2  Remove the patch, don't pull it back through.
