My remington vls 243 will be in this week. I was wondering what the best bullet would be to use for barrell break in. Also, some tips on breakin in would be greatly appreciated. Can't wait to shoot the new gun. Info will be greatly appreciated.

I always use factory ammo first with new firearm. If there is a problem with factory ammo there is no blame usually placed on the ammo by the manufacturer. I load 100gr Core-Lokts for my .243. The are accurate and inexpensive. The break in procedure is burnishing the barrel with bullets so cleaning often is needed. Sweets 7.62 solvent or others that have ammonia are normally used to get the copper out of the barrel. Don't let it work more than ten minutes since ammonia can etch the metal if left too long. Get a nylon brush (maybe two) to scrub the barrel while the solvent works. I say nylon because the bronze brushes will leave more "copper fouling" when used with the solvents with ammonia. How often (between how many shots) to clean is up for debate. You can go to the barrel manufactures sites and read up on their recommended methods.

The burnishing of the barrel is what you're after. Factory barrels are not lapped. (something you pay for dearly with a custom rifle) And something you can't really do after the barrel has been crowned and chambered so you have to smooth it out thru cleaning and shooting.
Good info already posted. I don't think a barrel can count so if it takes, say, 200 rounds to "smooth out" the bore, it doesn't make any difference whether you fire them in groups of 1 or 10 AS LONG AS YOU DON'T LET THE BARREL HEAT UP. Copper build up is another issue. I think one of the shoot one, clean one concepts was so the copper fouling wouldn't get too far ahead of you.
When I'm breaking in a new barrel, I like to use some JB's to help with my cleaning.

Thanks for the information. I picked up my new gun Monday. I brought it home and adjusted the trigger a little. I was pretty supprised that the factory setting was only 5lbs. Best I've had from factory in a long time. I lightened it up though. However, I have been really sick and haven't been able to get out and shoot it. Hope to get to today.
