[QUOTE="tim_w, post: 1818667, member: 11132"] Why not put up chamber/reamer drawings so you can get a comparative to see differences? I have only heard the tern "bore-rider" use to describe bullets. Bullet main body bearing surface bore diameter with numerous thin drive bands groove diameter to seal the bore but significantly decrease engraving and frictional resistance. In a chamber as I was taught and see in techincal prints and definitions. Neck>Step>Freebore>Leade>Bore Step+Freebore+Leade=Throat Step typically 45° centerline. Freebore is the, usually, parallel @ groove diameter to + 0.0005. Leade 1-30°+ to centerline. Throat is the sum of all 3 lengths. [/QUOTE]
