Does it increase accuracy? I have no idea, because that there is no way to test. You can't UN- break in a tube to re test. And all bbls are different, even tubes from the same mfgr..in the same caliber...from the same lot of steal, chambered by the same smith and reamer, shooting the same lot of brass, bullets, and primers....ect.
Does it increase tube life? I have no Idea...you can't shoot out a tube and retest....see above.
But, what it has done for me...with every factory and custom tube I have had for the last twelveteen years....is make the bbl clean up faster and easier, with less copper fowling. Will it extend the number of accurate shots between cleaning? Well, I am the wrong guy to ask, as I am a CLEAN FREAK and clean WAY to often. But when I clean a tube that I have broken in, the cleanup is fairly strait forward, quick and simple. Before I got into SERIOUS LR benchrest, and before I started breaking in bbls the cleaning process sometimes took DAYS.
But the phrase "the whole barrel break in crap" is...well CRAP.
And you have no evedence that there is no evedence.
It is very simple. The reason you break in a barrel is to reduce the rate it fowles.
Most barrels shoot their best clean, and then at some point if you keep shooting without cleaning
accuracy will fall off. It may not be much but it will fall off to a point.
Some barrels will shoot 3 or 4 almost in the same hole and then throw a fly-er. others will shoot
more (Like 7 to 9 more before accuracy is affected.
If you think about it fouling is not consistant so the each shot has to deal with different conditions.
A barrel that has not been broken in will foul faster and be harder to clean. I know this for a fact
because I tested a rifle buy firing 50 rounds through it and keep tract of the groups.
after about 4 hours of cleaning I then proceeded to break it in using the shoot and clean method.
Groups dropped dramatically and if I cleaned after every 5 shot group accuracy was better by 50%
or more. If I stopped cleaning the groups worked there way back up in size. Also this rifle would
shoot good tight groups until it reach 6 or 7 shots without cleaning.
So In my opinion, breaking in a barrel improves overall accuracy and slows the rate of fouling
so I break all of my rifles in and clean as often as possible and try never to reach the point of
When I first started working on other peoples rifles I found that most of them just needed a
good cleaning to restore there original accuracy.
This will not change some peoples minds and so be it, I will keep doing what I am doing until
something changes my mind.
