I just picked up a brand new Kimber mountain ascent chambered in 280 Ackley improved I'm wondering what the proper barrel break in procedure on these pencil barrel would be. I was thinking about just buying a couple boxes of cheap Remington 280 rem ammunition. That way I can fire form brass and do the barrel break-in at the same time

Break in seems important on a new purchase, but funny enough is never questioned the multiple times used guns come and go on the EE. If it was so important, how come rifles aren't listed with "certificate of break in" or pics of the cleaning patches?

I'm not sure about the benefits of breaking in a barrel but when I got my Mountain Ascent 270 win I bought cheap factory ammo and cleaned the barrel every five shots for the first 40 rounds if I remember correctly. After the break in I shot my first two groups, then I posted a picture of my target here on gunnutz, lol. Good luck with your new rifle. I don't think you will have trouble finding the right load, those 84L's are accurate.

Clean the carbon out of it in between the first few shots to zero, then after every 3 shot group for 3 or 4 groups then your good to go, biggest thing with pencil thin barrels is the heat up quick so be mindful of that, my KMA 270 win is a tack driver with factory barnes 130gr ttsx, I won the rifle and as soon as I got it home I dropped it off to Gary Flach had it bedded, the trigger lightened and the mag box freed up, its a dream to shoot and crazy accurate.

The best read on the how's and why's of barrel break in...

For an effective break-in the barrel should be cleaned after every shot for the first 10-12 rounds or until copper fouling stops.

This makes you wonder why you would need anything else, lol
Thanks for this! As someone who has shot almost exclusively second-hand rifles (my grandfather's, mostly), I was completely ignorant of the need to break in barrels. I knew new barrels had to be cleaned, but nothing like this. This article will be really helpful when (hopefully soon) I buy my own new gun.

Your right Pete......The reality is you don't need anything else......but since I don't golf or play bingo I gotta have a hobby......and what better than playing with rifles and reloading !
