Barrel break in.

36. “Breaking in” a rifle barrel is probably just a waste of time. Some barrel makers recommend it while others do not which demonstrates a lack of universal agreement on whether it’s really necessary so it probably is not. Every formula for break in involves some combination of firing and cleaning. The fact that there are numerous different formulas should be evidence that nobody really has the definitive answer on the best procedure meaning there likely isn’t one. Simply shooting the rifle as intended will likely be all the break in that is required.

that would only possibly be true if all barrel makers were making identical barrels out of the same types of steel, with the same coatings, using the same types of reamers, and the same mechanism for rifling (cut vs button vs hammer forging)


herohunts, welcome to THR. we normally have this question asked about once/month, but lately it's been at least once/week. please do a search
 
While the very first and very last sentences in SaxonPig's post are clearly speculative, everything else in his post is factually correct. :neener:
 
This is a quote from the website of Shilen Rifles, Inc. If you don't already know if them, they make custom barrels for precision shooting. "Shilen, Inc. introduced a break-in procedure mostly because customers seemed to think that we should have one. By and large, we don't think breaking-in a new barrel is a big deal." http://www.shilen.com/faq.html#question10
 
The main thing I do is to make sure I clean out any preservative that the factory left in the barrel. Some patches and brushes of Hoppe's.

Other than that, not much. The idea of barrel break-in is that the rifling needs to be burnished and de-burred. I THINK, that if there is any benefit to this, it is probably in the first ten rounds. I also think, you would have to try a lot of different procedures on a lot of different barrels to see any difference at all.
 
Hello friends and neighbors // I clean mine just to have a zero or known starting point.

I run a lightly oiled patch down the barrel. If I see any metal shavings on the patch I use a brush for a few strokes and try a patch again.

I also oil and then work the action in field position/stance.
I break in the barrel when I am sighting in the scope or iron sights. This usually takes several three shot groups (for me) at 50yards then 100 yards. Once I am on target at 100yards I clean the rifle (as per the manual)and check one last 3 shot group.
If it is going in the safe I'll clean the bore again. If I'm preparing for hunting season and constant use I leave it alone.

As for ammo...using Remington core-lok in 30-30 and 30-06. I have gotten white tail, one shot and drop kills, from 50-200 yards ( I hunt S.C. brush country) . I can't say about 270 ammo .

Welcome to THR, I hope you enjoy the Marlin.
