1. does it matter what ammo you use for the break in of a barrel?
2. what is a good ammo to use in 300wm to break in a Krieger barrel?
3. where is a good place to buy the ammo ?
4. what match grade ammo to use?

Shoot whatever you plan on using for non break in ammo.

Just buy some ammo and start shooting. Barrel break-in is black magic combined with voo-doo.

I'm not knowledgable on who's making match ammo for the 300 aside from Federal GM. Most guyse here re-load.

Really all you should be watching for is copper and how much it picks up. I have a Kreiger 30 cal and it was a hammer from the first. Picked up very little copper, I expect you will see the same as they are very good.
You can start your load development or buy a couple different boxes of ammo to see what shoots the best immediately, anything else will be a waste of money.

I use the method Krieger describes on their website for all new barrels, not so much a break-in as a scrupulous cleaning regiment to prevent copper buildup during the first shots.
Feed it the same diet it's gonna live on.
There's nothing you are going to accomplish by shooting a premium barrel to improve it, it's just wearing out from the first shot on.

Nope

2. what is a good ammo to use in 300wm to break in a Krieger barrel?

Any reputable name brand 300wm ammo should work OK.

3. where is a good place to buy the ammo ?

At your favorite little ammo store.

4. what match grade ammo to use?

If you think you need "match grade", consider getting Federal Gold Medal Match (190 Sierra Matchking), or Black Hills, loaded with the 190 Sierra Matchking. Be advised that if it does not seem to work well for you, the problem is probably NOT the ammo.

You might contact CopperCreek and see what 300WM they are loading.

After many years (30+) of trying a variety of barrel break in methods, I finally settled on this:
1) Get a good quality bore guide, remove the bolt and put the bore guide in the action.
2) Using a good quality cleaning rod, properly sized, with a correct size jag, run a clean patch or two through the bore to remove any grit, shavings, or debris.
3) Remove cleaning rod, and remove bore guide.
4) Reinstall bolt.
5) Shoot whatever ammo I desire, at what ever target or distance I prefer.
6) Repeat step 5 until barrel replacement is needed.
7) Repeat steps 1 through 6.

Southwest ammo has great ammo. I agree with above posts.
