I'm the proud owner of a new Tikka rifle and am wondering what all to do with a new rifle to get it ready for shooting. With my first rifle, I cleaned it all very thoroughly and then went through the whole barrel break-in process. From everything I've read, it sounds like barrel break-in is unnecessary. What sort of cleaning is needed, though? Seems like wiping off excess oil and cleaning the bore is worth doing. Anything else? I have seen videos of people disassembling the bolt and cleaning excess oil off the bolt components as well.
