I have an Omega in stainless and just shot it last week for the first time. I fired 12 rounds through it (Shockwave sabots) while running a spit patch through after each shot. Back home, I cleaned it with hot water and T/C bore butter. I wiped the swinging breech portion and it was dirty. I also ran some cotton swabs into the trigger assembly and they came back dirty as well. I decided to take the stock off and completely clean the breech and trigger assembly. My questions are as follows:
1. Is the fouling on the breech and trigger area from the primer or blowback from the powder?
2. Which is more corrosive, the powder or the primer?
3. Also, if I have to take the rifle apart (removing the stock), won't my scope be slightly off next time I shoot it creating the need to sight it in again? And in turn the shooting will cause me to have to take it apart and completely clean it again starting the cycle over. What do I need to do?
