I have a Browning Xbolt Medallion on the way from Buds and was curious what the OB opinion is on breaking in a new rifle. It's been a long time since I had a new one, but I don't recall ever doing so in the past with my dad. I've shot a Ruger M77 for years that has been very reliable without any known break in. All that said, I don't want to screw up my new rifle. What y'all say?

You dont have to do it but it can make cleaning it easier. Just Google the method. I think its shoot once, clean, repeat 5 times, 3 shots clean, repeat 5 times and 5 shots clean. It should be easier and faster to clean it. It also removes the tooling marks in the barrel.

Meh, it will break in faster than most think.

After a few rounds is clean it and then use it like normal.

I never touched the barrel of my 260 until a couple hundred rounds were fired.

couldn't hurt to pull a bore snake before shooting it, I'd guess some do more damage with a rod than good

this page has a good explanation

krieger barrels break in

"When the bullet is forced into the throat, copper dust is removed from the jacket material and released into the gas which at this temperature and pressure is actually a plasma. The copper dust is vaporized in this plasma and is carried down the barrel. As the gas expands and cools, the copper comes out of suspension and is deposited in the bore. This makes it appear as if the source of the fouling is the bore when it is actually for the most part the new throat."

I have done this on a couple of rifles. Let the barrel cool in between each shot (of course). What's it hurt if it doesn't do anything? Nothing.

ETA-they were both Browning A-Bolts and easily shoot MOA or better with the right ammo.

ETA2-Obligatory OB response, "It doesn't matter if it ain't a Tikka because it ain't gonna shoot worth a shite anyway."

If I bought a Sako, I would buy a bore guide and definitely do it. It cant hurt anything.

I clean and lube every new gun I get. After that I just shoot it.

Here's our process







































Shoot it
Don't clean it

You season a cast iron skillet, why not season an expensive rifle barrel.

Because my rifle barrel isn't made of cast iron?

Clean it good before you start.

Sight it in. Use a nylon brush to remove powder and oil it up.

I do not run a copper brush or bore snake until I am ready to resight in or change ammo.

Some competitive shooters do not remove the copper until the primers start to deform. They say more copper filling all the imperfections in the barrel improves accuracy.

IMO, I would only do it if needed. This day and age you really shouldn't need to on a quality production barrel. In the age of the CNC and modern machining practices and tooling; production barrels should not have a whole lot of fouling/tool marks from quality producers. Now, a barrel chambered by your local smith on his 1940s South Bend probably will need to be broken in. Really, the barrel should tell you. Shoot a 5 shot group, let it cool and then shoot another 5. If the group has opened up substantially you'll probably need to break it in.

I have a Blackhole Weapon barrel on my AR-10. Love the barrel and it's very accurate. It came with instructions to break the barrel. Pretty easy though. 20 rounds. Shoot 5 run an brush through it, 5 rounds, clean, etc.

I would like to see what kind of groups that 700 produced. Odds are they were still very good. The hand lapped barrel would obviously be easier to clean but does that necessarily directly correlate to more accuracy?

My thinking is that you have $1,000 minimum invested in the rig. Often a good bit more. Do everything you can to make it the best rifle it can be.
