Careful of the front of the barrel as it is probably crowned though (slighly smaller than the bore).
The crown is the transition between barrel and open air… the slight angle you see right at the tip. Your thinking of the choke, which is a narrowing of the barrel at the muzzle end.
I only ever use bore paste on new barrels. Give them a few passes with an oild covered rag to get any large debris out, and then a few rag’s covered in the paste and then pass clean rags through until all the paste is gone and then I only ever pass oiled rags through the barrel after that, and even then only if I’m going to store the gun for a long period of time or if I notice a problem with accuracy.
