Mass produced box store rifle barrels that are hammer forged or button rifled and never lapped before they leave the factory are a whole different animal. The more you shoot a store bought gun the better they get(usually) because every shot is actually doing a tiny amount of fire lapping and over time the lumps and bumps down the bore are smoothing out and multiple cleanings to remover copper fouling is also doing some micro lapping. That's why sometimes you see a gun start to "come around" after a couple of hundred shots. I also believe that some guns that shoot better dirty is because the copper fouling is filling in those low spots and chatter marks from the button mandrel and thereby making the bore smoother. High end bore scope will show you a lot of stuff you never knew about and will leave you scratching your head about how the gun even shoots sub MOA. Only takes one good look down one of them cheap ugly old Savage barrels and you wonder how is it possible. After all them old Savage barrels are hand straightened by eyeball on a manual press and by a 3rd generation employee whose father and grandfather did that job before him. https://www.facebook.com/watch/?v=1837719936336570 But why are they shooter? Why does Savage recommend breaking them in?

Well. if you are doing precision, long-range shooting it may be a worthwhile investment. If you follow some directions you will shoot over 100 rounds, which, at store bought, or even reloaded prices is a pretty significant investment. And for what?
I paid less than $300 for a rifle last year, before I ever heard about barrel break in. I shot many groups, but one 5 shot group at 100 was .358" and one 3 shot group at 200 yds was .403".
I also got a RAP this year that will consistently shoot 1/2 to 3/4 moa groups all day long without the break in procedure. That is plenty good enough for me.

FWIW, recently bought a Christianson 300PRC. Recommended break in was 50 shots. I performed the recommended sequenceand had no color on the swabs through 20 shots. NONE! I will add that it didn't really start shooting right until I stopped cleaning and ran another 15 shots through the barrel and got it dirty.

I believe the average rifle owner will do more damage to the barrel (throat and crown) by putting the brush through it 5-10 times than any amount of shooting will.

I break my barrels in with a fresh target and lots of ammo, I believed in that years and years ago and I never saw a single difference so I stopped doing it. I do clean them pretty often but I always send a single round down the tube to foul it before going hunting with them. Some guys swear by breaking them in and others not so much, me not so much.

Originally posted by trophy8 View PostI’ve never believed in a barrel break in. I’ve done it to a few. I took out a rifle I put together a month of two ago.
Impact 737 action
Foundation MG2 dark distressed
Proof prefit comp contour 26” 1/7.5 6mm creed
Trigger tech diamond set at 8 ounces
Atlas BT46 with RRS arca adapter
Foundation full length Arca rail
Hawkins M5 DBM
Hawkins heavy tactical rings
Leupold mk5 5-25x56 PR2 mil
So you think a barrel needs broke in to shoot well? I decided to just seeeeeeeend it today. No shoot and clean. Just straight up sight it in then run heavy strings of fire.
Factory Berger 105s.
Here’s the rifle. Then here’s an 11 shot group as fast as I could load em and shoot at 100.
