Barrel break in and copper fouling

[A5BLASTER]

What exactly is the role of copper fouling on a new barrel?
I've heard some say a little copper it's beneficial for accuracy, other places say to remove the copper during break in.

I was planning to pull a boresnake through it every 5 shots for the first 75 rounds. Would it be helpful or detrimental to use a dedicated copper remover during this time?

I use a boresnake of sorts. I use the Otis snake with screw on attachments for cleaning.

But here is where I'm at with barrel break in. I use to go through the whole routine of shooting and cleaning x number of shots for y number of steps.

Then one day I decided to test it and see if it made a diffrence.

I bought my first of many of the 16 inch AA barrels I have. Didn't do any break in at all. What I did was keep my rate of fire low enough that I could never feel with my hand hardly any warmth in the barrel. Did that for the first 100 rounds.

Then I stripped the barrel clean got everything out, carbon, lead, copper everything. Went to the range and resighted and that barrel will shot everything good to very good and shoots factory fusion into stupid small groups.

So I took a second matching barrel and built in to a matching upper, did the whole shoot and clean routine and even went beyond that and didn't let my barrel get even slightly warm when it reached 100 rounds I stripped cleaned it.

And guess what both barrels shoot just as tight with the same ammo.

What I have noticed is if you buy a top end barrel that has been hand lapped. There is even less of a reason to do the break in thing.

To me break in is a waist of cleaning supplys and range time.

Now this is for me, I'm not going to tell someone they shouldn't do break in. I'm just saying from what I have seen with my own barrels it's not worth the effort.

But I also don't buy dirt cheap barrels. That maybe the biggest factor in all this.
