I just purchased a 270 wsm in a tikka hunter. I have never worried in the past but I keep hearing about "barrel break-in". Any thoughts or should I just go shot it.

This is one of those religious areas for gun loonies. Some say yes, some say no. John Barsness recently wrote an article saying no. Kenny Jarrett says you need to do it to blend the machining zone of the chamber (rotating tool marks) with the barrel machining (longitudinal marks) to keep from forming a donut of alternating powder/jacket residue at the junction.

Some barrel makers endorse break-in and you can find instruction on their websites, some don't.

I follow the shoot one, clean one routine for the first 20 shots when I am also mounting the scope and sighting in or whatever. For me it has never made a barrel shoot worse, and perhaps makes future cleaning easier.

voodoo.. seems to work for some, blather for others... your first X shots aren't doing anything but smoothing the barrel.. do what you like to get there

Well trying to think. I did break in my BR barrel. Or at least the shoot clean for the first few.

Hunting rifles. I take them and shoot them. Factory and custom. Shoot it don't overheat it and clean it when I get home.

No down side to breaking the barrel in.

Barrel break in

for a hunting rifle?.....

Tikka does guarantee 1" groups and picking the right load will better that .What's the problem ?

Not only do they have the accuracy guarantee, but Tikka's technicians would have already shot that rifle to make sure of it, like they do with all of them.

Dan-oz (or anyone else) does this mean the Tikka barrel is already broke-in?

cannot confirm this....but seriously doubt it!

I actually had a guy contact me to find some 7MM WSM moly coated ammo.....I asked why as this is not so easy to find....he told me his gunsmith told him to breakin the barrel using molycoated ammo....he's not a reloader.

I told him to find another gunsmith!!! This is pure malarky.

There is no proof or concrete evidence that barrel breakin is of advantage to the owner of the gun.....hunting rifles I mean.....

Either that, or Tikka's technicians think "breaking in" processes are hogwash unsupported by scientific evidence too

The answer is obvious, but, many misinterpret the answer.

This is one of the better stories I've heard on this subject! For some reason, I've never found such a donut in ANY of my modern rifle (or handgun) barrels. Nor in any of the muzzleloaders either!
