Sorry if this is in the wrong section. Not sure where to post it. Just a few ???? here. I just purchased another 300 RUM and its the 700 SF ll. Part of my barrell break in is to start by cleaning it when I first get it home and before I shoot it because I know they test firearms before they leave factory. Heres my question. How many times do they shoot each rifle? I ran a Nylon brush down the barrel soaked in Tetra Gun and let it sit for 10 min each time and then ran a dry patch. I did this 18 TIMES before there was no (blue) copper fouling. I realize they test at the highest PSI and these cannons like to leave behind fouling, but it seemed a little excesive to me. Do they use blue bullets??? Lol. Thanks for any advice.
