Breaking in a new rifle barrel. Need to or myth?

[Biggerhammer]

My Benchmark .338 Edge shot well right out of the gate! Patch-Out with the patch out accelerator works wonders. Just a jag and a patch. Nothing else has ever touched the bore.

First 300 yard group 1/2" inch.

Gotta love a non-belted power house.







The 285gr Hornadys flat crush Mulies!

Some true snipers on this forum. I'd hate to see all the good groups!

👌There are some amazing shooters, some actual ex-snipers I have shot with, hunted with, and competed with many of them. There are also some chest pounders on this forum that its fun to watch and read their posts. Most know who they are 😉
In regard to the OP, the recommendations from those here that follow manufacturers recommendations (the ones who build their barrels, obviously are the ones who know proper procedure, and don't just offer advice for the sake of the "snark"👍

You would be surprised at how well allot of members here can shoot. That's what they do, thats why they are here. I'll bet on a serious varmint/Predator hunter everyday. Over a guy shooting a steel plate the size of a 747 at 431.3 Meters. When the other can hit Rockchucks laying flat (4" vertical
Target) 2 for 2 at 602 yards, from the sitting off a bipod to boot.😃

No break ins for my guns.  Copper is a good thing.  This is my take on it
If you are a compition shooter who's rifle will need cleaned after each session than a break in will help it clean out faster. If your not the kind of guy that needs to clean a rifle after every match then copper equilibrium is better. Jmo

best group of my life was shot off my bipod sitting position.  Who needs a bench anyway

After firelapping - factory 338-378 w 300 grainers @ 2850. 
Sometimes crazy stuff just works.
4 shots duplicated with 4 more.

That's awesome my factory MV doesn't shoot like that, It's probably me though.

Sweets and patches have worked good for years for me

Don't make a lick o difference.

Not so much in accuracy, but Definetly lessens cleanings between shot strings, and makes those cleanings simple and quick. Proven! 👍

Gotta bed those weatherbys to get them to shoot.  And with the big jump they like some bullets and some they don't.  I couldn't get the bergers dialed in.

understood, Mine will not shoot the SGK, but it likes the SMK, and the Partition.

I finaly got to the range. I thought I'd try to break in my .270 Winchester. I wasn't trying to  get clover leafs just in the general area. The first two rounds were off target. Thanks to the guy a couple of benches over for getting me on the paper. 30 clicks right and 30 clicks up and I finally got on the paper. The 3 low ones. About 20 more clicks up and I was in the right area. Shot 10 singles and cleaned after each. I used Sweets, a .270/7mm jag and pre cut patches. Couple of drops of Sweets on the patch and slide it thru. It took about 6 patches after each shot to clean the barrel up. Never did drop to 2 or three. I did get to shot 2 groups of three and clean up after each 3. The ammo I was shooting was Winchester Deer Season 130 grain extreme point. MV 3060. Leopuld VX2 3x9x50.

Put one of those black dots in the center then try some different ammo 

[Badhabit]

Will do. I actually like the targets with the vertical and horizontal bars. They seem to help my accuracy.
