QUOTE:but I had read somewhere about needing to clean the barrel after each round for a certain # of rounds and also some other steps that sounded like a real pain.
Rotto,
What you are referring to is the procedure more along the lines of what a bolt action target shooter would follow in a quest for accuracy.
The procedure is to remove the action from the stock of a rifle and pour boiling water down the barrel so the "pores" of it expand and release impurities. While the barrel is still hot you would then hand lap the barrel (basically polish it) with lapping compound available at some finer gun shops, or suppliers.
You then proceed to the range and clean the barrel after every third shot until you've gone through 40 rounds. This supposedly breaks in the barrel and smooths the lands without causing impurities to catch up and build up in the barrel before you've had a chance to breakin the barrel with natural break in.
Yes, I've done this and it is a pain. But, I don't think this is necessary with an assault weapon, as it would Kind of seem like overkill unless you're competing in the Nationals. (As Bart was also sought of saying)
Though, I tell you what..... it might be worth it when buying that DPMS .308 heavy barrel Assault rifle that shoots .75 groups or better @ 100 yards. (I don't remember the model) If DPMS gets around to putting the post post ban goodies on that bad boy, I'd like to buy it! (Though I'm getting broke real quick 2 days after the ban already!
)
