One last comment, the key to any barrel performing to its top capabilities is a proper barrel break in. If it take 100 rounds, so be it.
In my experience, far to many shooters rush the barrel break in process and the result is a barrel that copper fouls more then it should.
I recommend a 50 round barrel break in proceedure to my customers, even with the Lilja barrels I generally use which will polish up on averge in 10 to 15 firing.
Here is the proceedure:
Fire two rounds and clean, fire two rounds and clean. Do this for a total of ten cycles or 20 rounds down the barrel.
Then shot three rounds and clean, three rounds and clean for another 10 cycles or 30 rounds total.
I have yet to see a barrel need more then this but if they do, take as long as you need.
One hint to breaking in a barrel. Most use the cheapest bullets around which is fine but these are also generally the lightest bullets around as well.
Actually using a heavy for caliber bullet will get you more bang for your buck because there is more baring surface working for you on teh bore finish. This is just a theory of mine but it seems to work.
With a 30 cal barrel, it seems that a 180 to 200 gr pill will polish up a bore in fewer shots then a 150 class bullet will.
Good Shooting!!
