Ive just recieved my first ever rifle, a Browning X-Bolt Medallion in 30-06 and I was wondering if I were to go to the range with (for example) hundreds of rounds, after how many rounds would the barrel need a really good cleaning? Or after a certain amount can I give it a quick wipe down with a couple patches and continue shooting? Ive already broken in the barrel and would be shooting 180 grain federal (for information sake). Last question is how hot do you let the barrel get and how cool do you let it cool down? Im not looking for exact temperatures just something to wrap my mind around.
