Rem 700 Barrel Break In Process

I have a PSS 223 arriving in about 10 days. What is the "best" barrel break-in proceedure. I have heard the
- shoot 1, clean, x5
- shoot 3, clean, x5
- shoot 20, clean x10
or some close variant on that. BUT... clean with what ? Bronze bore brush though a bore guide with Hoppes #9 finished off with a swab with a drop or two of oil ?

Or... any insights appreciated.

  You'll probably get 10 replies telling you 11 different ways to do it FWIW, here's the military's procedure for the M24 SWS.

  Here is the S.G.&Y. (Benchrest barrels) methiod
  http://www.benchrest.com/sgybreakin.htm
  
  Shooting is the 4th step
  1. Clean barrel / lube bolt / 1 shot.
  2. Clean barrel / lube bolt / 5 shots.
  3. Clean barrel / lube bolt / 10 shots.
  4. Clean barrel / lube bolt /10 to 15 shots and clean again.
  
  Here is the army methiod mentioned above
  
  d. Barrel Break-in Procedure. To increase barrel life, accuracy, and reduce cleaning requirement the following barrel break-in procedure must be used. This procedure is best accomplished when the SWS is new or newly rebarreled. The break-in period is accomplished by polishing the barrel surface under heat and pressure. This procedure should only be done by qualified personnel. The barrel must be cleaned of all fouling, both powder and copper. The barrel is dried, and one round is fired. The barrel is then cleaned again using carbon cleaner and then copper cleaner. The barrel must be cleaned again, and another round is fired. The procedure must be repeated for a total of 10 rounds. After the 10th round the SWS is then tested for groups by firing three-round shot groups, with a complete barrel cleaning between shot groups for a total of five shot groups (15 rounds total).
  
  The barrel is now broken in, and will provide superior accuracy and a longer usable barrel life. Additionally, the barrel will be easier to clean because the surface is smoother. Again the barrel should be cleaned at least every 50 rounds to increase the barrel life.
  
  Either way your only looking at 25-30 shots fired.

  Some guys like a mag full of lead, I still prefer one round to the head.

  Both of the ways listed above sound close to what I do. Just pick one or the other, and go with it. That round recoils so little, you can break it in in one afternoon, then re-clean it and start grouping. And yes,....it does make a difference. That is if you are concerned about groups. Some guys are happy with 1" at 100yds, that just don't fly with me. If it isn't a one hole group, it's to the gunsmith, if it still isn't a one hole group, it's for sale or trade.
  
  
  
  A great rifle with a junk scope,....is junk.

  most ways are good, I go 1 shoot clean 5 times. Then 3 shots clean 5 times. Then a string of five clean five times and by that time I'm tired of cleaning!! It's however you feel comfortable, just clean it alot.
  
  New gun??? No, honey, I've had it for years.

  Any of the above ways mentioned should indeed be a treat to your barrel.
  
  
  Good Luck.
