[QUOTE="J E Custom, post: 1772065, member: 2736"] You have heard many opinions and theories and that Is why I run test to prove one way or the other. Some of my test have shattered my beliefs and theories because so many people told me that It was a fact. In my post I referenced a test that In my mind convinced me that a brake in was necessary on all barrels the get it performing at it's best. I also did another test later own to back up the results and it did. It was a much lower velocity test but the results were amazingly similar. Some of the arguments I have heard are = Adds to the round count. I have found it does just the opposite by allowing load development to start sooner and be achieved with less rounds fired. Before I started breaking in my barrels it was not unusual to take 50 to 100 rounds to find an accurate load. Some even took more. now while breaking in a barrel I do some component changes to see if there is a trend and sometimes this gives me a jump on the load development when the barrel is broke in. Now most of the time i find a good load in less than 20 or 30 rounds. I feel one of the reasons is that the barrel is more consistent in this state. I also hear that copper fouling has to be laid down before accuracy will peek. All of the best groups I have shot have been with a clean barrel. It is true that at some point it will shoot if fouled and when shooting 100+ shot matches with no chance of cleaning you have to rely on this method, but you must work up your load in the fouled condition if you intend to shoot this way. With a properly worked up load for both conditions, A clean bore will normally out shoot a fouled bore because the fouling in a bore is not consistent, and a clean bore is/can be. Like everyone I know that has tried it, they all see the advantages and the accuracy improvement by doing a brake in. I have no intention of trying to change peoples mind about brake in and all I can do is offer my experiences of 55+years of shooting, hunting and building accurate rifles. I use the vary best barrels and the only difference I can see when braking in a rifle is the number of shots required to reach brake in. Just my experience J E CUSTOM [/QUOTE]
