Is there a type of bullet that is better/worse for breaking in a new barrel?  Are the coated Winchester Ballistic Tips ok or will good 'ol plain Core Lokts work just as well?
Thanks.

Does not matter just shoot what you normally shoot. Cheap is good.

I don't partake in the break-in kool-aide...Just shoot it!

That's what I was thinking.  I read somewhere a person should use a jacketed bullet during barrel break-in, but they didn't say exactly why, so I was curious what other people did.
Thanks.

Well, nearly all modern hunting bullets are jacketed. An exception would be Barnes. Their tsx line is solid copper. Any normal hunting (or Target for that matter) bullet will work fine for "break in" which I also do not partake in, and consider to be voo doo.

There is much voodoo in the break-in world, and there is no "one-size-fits-all" answer.

The purpose of the break-in is two-fold.
1.  Smooth out the rough edges and remnant pieces of metal left in the barrel after certain types of rifling.
2.  Deduce initial copper fouling for more uniform surfaces.


As a general rule, barrel break-in has never made a barrel less accurate (assuming one knows how to clean a barrel.)  But, not breaking in a barrel has absolutely made many barrels less accurate.

First exception: custom barrels are quite often hand-lapped and very, very carefully gauged.  These should have no uneven surfaces or remnants left from rifling.  That said, I usually fire and clean a few cycles, to be sure the bore isn't holding copper.

Second exception: "what might have been", after breaking in or not breaking in, you can't go back and test the antithesis.  If your gun is a shooter, you'll always wonder if it might have shot better with a good break-in.  If it sucks, you'll always wonder if it would have been a shooter...

I break in all my barrels (using standard "fire 1 and clean", till I get no copper fouling, usually 5 singles or so. Then a few strings of 3 to 5 then clean.)  WIth custom barrels, they usually only require a few singles, and they never really hold much copper anyway.

Break-in doesn't hurt, and it damn sure might help.

Lastly, avoid moly-coated bullets for break-in.  Moly is another voodoo area; however, there are issues with moly (trapping moisture, layering unevenly), so it is best not to run moly and only moly, especially on a brand new barrel.

How's that for a post with which everyone can find something to disagree!

While I think barrel break-in is a little bit voodoo myself, this is sound advice from RC.
 
Also that coated winchester "lubalox" stuff can really jam up a barrel. 
 
All-copper bullets are softer and won't smooth out a barrel the way gilding metal jacketed bullets will.
 
I shoot a couple singles, clean, and clean after five for four cycles of five.  I use cheap jacketed bullets, and also do my initial zeroing.

Thanks for the info. 
 
Since I have to use factory loads for now...I'll just use the Core Lokts and clean the barrel after every shot for the first 4-5 shots.  I'd rather err on the side of caution than risk damaging a new barrel.
 
I use Winchester Ballistic Tips with my 25-06 (rifle loves 'em).  Would it be smart to run a few non-coated rounds through it everyonce in awhile to clean out any of the coating that gets left behind, or is a good cleaning good enough?

If you mix coated and non-coated bullets, you can compound the fouling problems.  I would suggest cleaning often with an all-purpose cleaner like Wipe-Out if you are going to use the coated bullets.
 
I am shy about them, though, because I had a Savage 270 WSM I just couldn't keep clean using Lubalox bullets.  I never had any trouble with non-coated bullets.

That's good to know.  I probably don't go through more than 50-60 rounds before it gets a good cleaning, with the occassional bore snake in between.
 
As to using the coated Winchesters...I've tried both Hornady's and Core Lokts, but I couldn't get this gun to group worth a crap, unless I use the Winchesters.  My 243 loves the Hornadys, so I don't know what the deal is.

Use what you would normally shoot.  I do not use the the Moly coated bullets for two reasons, I do not notice any increase in accuracy or range, and the moly is a real bear to get out of your bore.

A good break in will not hurt your rifle and even if it does not make much difference to a high end hand lapped barrel, it will still teach good practices to the shooter.

There is no cut off date in a barrels life for break in, I have found it to improve 100 year old service rifles as well as newer sporting rifles I bought for a song because "they would not shoot anymore"

I have spent literally hours posting break in info to the internet.  Follow the link, read the instructions, the commentary is up to you, but answers many questions.
