Do you guys use a chamber brush on the 338 lapua? I am going to get the chamber cleaning kit with those round cotton swabs, read good reviews on them. just wondering if I need a 338 chamber brush too?
For my .338 I have been using a cotton shotgun mop. Not sure of the size because I just grab the one that fits. I only use the mop because I have OCD. I only feed it tumbled reloads, have a bore guide with O-rings, and don't shoot too much to begin with.
