Spent the morning at the range sighting in a new scope on the 6.5 creedmoor. I'd picked up some 140 gr Sellier & Bellot soft points not too long ago and shot several groups with them getting things dialed in. Overall, they shot pretty but when i got home I was amazed at how dirty the rifle was. Seems like it took me forever to get that barrel clean. Anyone else had a similar experience with Sellier & Bellot ammo? I know it's cheap ammo but it seems dirtier than most.
