That's what I was doing..... here's a picture I just took of the inside of my 270 Marlin XL7. It's a pretty good shooter but look at the inside of that Barrel ouch. Up by the Chamber of things are pretty smooth but the further you come down the barrel the more it starts to look like a fireman's ladder with tooling marks..... and they are everywhere on the lands and between them. Got to give Wipeout credit for getting everything clean they must get embedded pretty good as that bullet goes down there...
