guy said he shots once, cleans, shoots twice, cleans, shoots 3x, cleans, all the way up to 10x, then he's done, said its prob not the pro's method/best, but much better than nothing....wish i read/knew this sooner?
There are many different ways to break in a barrel, and if you ask a few different people if it works, you'll get different answers. I do "break in" all my new rifles, by shoot once, and then clean for the first ten shots. Then shoot five shots and clean the barrel. I do that a few times depending on how much time I have. I don't know if this improves accuracy, but it sure won't hurt. I have old guns that shoot really accurate too, and I know they did not go through a break in process. Bench rest shooters break in barrels religiously, so there has to be some good reason for they do it.
There are also a lot of products out there to help with the break in process. Bore creams and paste. Tubbs also has a system to break in you new barrel.
On a factory tube,before firing a shot, I"ll use JB's on a tight fitting patch for 30-50 strokes, flush it and shoot and continue to shoot until accuracy falls off .Factory barrels are not lapped so it's my opinion this will take some of the roughness out.
On my rifles that have high quality barrels, I'll do nothing but shoot em and shoot em somemore until accuracy falls off.
your milage will vary

This is my understanding of barrel break in. Basically your barrel was machined, as with all machined items, there are small spurs and imperfections inside your barrel. The idea is you shoot a round, and it starts to loosen those spurs or breaks them off. So you clean your barrel to get those out because they are in fact steel, and you don't want your next bullet pushing that spur down the barrel and maybe making small gouges in your barrel. You repeat this essentially as much as you have patience for.

The other side says; throw it on the ground a few times (then they pick up the rifle and hit a target at 600 yards).

Opinions on the worthiness of this procedure are varied. There are some people on this forum whose opinions and knowledge I value highly who differ among themselves about it.
.......Personally, I started doing barrel break-in on both factory and custom barrels more than a few years ago, and I believe in it's merit. I'll continue to use it.
