how do you break in a barrel 10 shots 50 100 clean between each shot? what do you clean with and have you ever used jb bore paste herd alot of good and bad about it. just wanted to see the ways others do it and how well it works for them

for my hunting rifle i just sent about 5 rounds down, cleaned, and repeated. now every 10-15 rounds i'll clean it. it shoots about 1/2MOA so that's good enough for a hunting rifle. my sako trg i read a lot on the subject and it sounds like most guys just say go shoot it. so that's what i did. sighted in the scope and cleaned it. shot it a little more working with reloads and cleaned it again. accuracy improved greatly after the first cleaning. I don't think you need to get too OCD about breaking in your barrel. but i'd recommend cleaning it 2-3 times between 25 rounds. I am in no way an expert...just my

Ruining the crown is the major issue I have heard about, poor cleaning causes problems

this is also an issure i have heard. the barrel for the most part won't alter...it's the entrance/exit that are important.

Another interesting article:

I've got a new Remington 700 sitting on the rest waiting to get sighted in and I'm debating if/how to break the barrel in.  I'll clean it before I shoot for the first time and then clean it after about 20-25 rounds or after it's sighted in, whichever comes first.

I've heard of cleaning after every shot for X amount of shots to properly "break-in" a barrel but that sounds a bit ridiculous to me...

thanks for the input i have done it diffrent ways and have not seen much difference but i have seen my 270 wsm go from 1/2 inch groups to 2 inch groups with copper fouling in 20 to 30 rounds with triple shock bullets
