Here's one way...

Or, make sure you clean it, then take it out to the range and put a box or two through it to see how it shoots. If you take it slow and clean it when you get home it should be fine. Bear in mind that you can kill the accuracy of a rifle by over-cleaning it or by improperly cleaning it.

I like to make sure that the bore and chamber are clean (a few patches made damp with Hoppe's No. 9 followed by a dry patch to soak up any excess) then use an over-sized patch on a .35 cal bronze brush for the chamber. This is to ensure that there's no oil residue in the chamber (it should be oil free/"dry" when you shoot it).

For ammo, if you don't reload, get some factory ammo from your favourite gunshop (try some Federal (or Winchester or Remington) 130 grain factory rounds. Although I've been a die-hard handloader for many years I've had surprisingly good results with .300 Win Mag factory ammo (just to see how a "new" (to me) rifle would shoot). Once it was clear that the rifle shot alright it was time to get reloading dies, etc. and reload the brass.

Above all else, become familiar with your rifle, be safe and have fun.:)
 
LOL. Thats hilarious. I have never been convinced about the science of barrel break in. I don't think these guys are either

I don't consider barrel break in a science,but I do watch more closely for copper fouling since there is often more copper fouling with a new barrel.

But it's also no science that I really don't have a use for the 270s.;)
 
If there was anything, whatsoever, to the myth of barrel brake in, I'm sure the manufacturers would have been passing on this information to the buyers of their products for the last 100 years.

Stubble, Here is part of the information you posted for my benefit.
Pretty much what I've been saying all along, isn't it?


Break-in procedures are as diverse as cleaning techniques. 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.

Shilen did specify that breaking in a barrel is no big deal,but had you continued with the quote,they also specified.

All our stainless steel barrels have been hand lapped as part of their production, as well as any chrome moly barrel we install. Hand lapping a barrel polishes the interior of the barrel and eliminates sharp edges or burrs that could cause jacket deformity. This, in fact, is what you are doing when you break-in a new barrel through firing and cleaning.
Here is our standard recommendation: Clean after each shot for the first 5 shots. The remainder of the break-in is to clean every 5 shots for the next 50 shots.

As per the Kreiger link.

So when we break in a barrel, our goal is to get the throat polished without allowing copper to build up in the bore. This is the reasoning for the "fire-one-shot-and-clean" procedure.

As per the Pac-nor link.

Shoot one, clean, for first ten rounds; shoot three, clean, for next thirty rounds; shoot five, clean, while working up load.

As per the Badger link.

For the first ten shots we recommend, if possible, using jacketed bullets with a nitro powder load. Clean the oil out of the barrel before each shot using something as simple as Windex which will soak the oil out of the pores. After firing each bullet use a good copper cleaner (one with ammonia) to remove the copper fouling from the barrel. We do not recommend anything with an abrasive in it since you are trying to seal the barrel, not keep it agitated.

Do you normally clean your guns after each shot?How about after every 5 shots?In other words,although all manufacturers don't have a complicated break in procedure,many do specify a break in procedure that varies from most peoples normal cleaning regiments.

I'm sure the manufacturers would have been passing on this information to the buyers of their products for the last 100 years.

Did tobacco products have health the health warnings on them 100 years ago that they have today?How about asbestos products?Why not?Because over time we have learned things that we didn't previously know.Most of us choose to accept what has been learned,but as with every society,some people prefer to live in the past.

The barrel break in theory is a wonderful subject for these threads, because no one can prove his rifle shot better/lasted longer, because it had a precise manner of starting out in life, as compared to just shooting and cleaning in the regular fashion. Nor, can I prove it doesn't work!
It reminds me of when I was taking the training to become a flight instructor. The instructor teaching drilled into us that we should never tell a student anything about theory of flight, if we couldn't demonstrate that theory in the air.
A simple example would be as follows. I would tell a student that if we move the control column to the right, the nose (of the aircraft) will first move to the left, before it starts to swing toward the right. The theory of why this is so, would then be explained to the student. Lastly, I would have the student move the control column of the aircraft to the right and he/she would see that the nose actually did move first to the left. The theory behind it was now clear in their mind.
If the theory of barrel break in can not be demonstrated, why are we wasting our time on it? Everyone should do what he believes is right, and live happily ever after.
I promise, I am finished with the subject.

That doesn't change the fact that your statement about the manufactures not passing on the information ,was incorrect.

They are the ones making the barrels,not you,so I do consider them to have far more experience and knowledge as far as barrels are concerned than you do.Since several of them specify,a barrel break in,I choose to accept that there may be a genuine reason for them specifying a barrel break in.I may not follow their recommendations to the letter,but I do treat new barrels a bit differently as far as cleaning is concerned.
