I have heard many different opinions about breaking in barrels.The problem is many of the techniques I have heard are complete opposites. I was taught that when you have a new barrel there are deficiencies in the barrel and to make the barrel smooth you need to fill those deficiencies with brass. The way you do that is by firing your gun then cleaning starting with a small amount of rounds fired before cleaning and gradually increasing the amount of rounds fired before cleaning. I was taught not to use Sweets or any solvents that breaks down brass. I have heard out of the factory most guns have around 50 or so rounds put through them just to make sure the gun works, so there is no need to break the gun in. I heard the other day that you must run Sweets through your gun to break the brass down because the brass builds up unevenly in your barrel. Now I do my fair share of shooting but I do not have enough experience to say that one way works best. Does any one have some advice? Thanks, Tyler
