Is the rifling on a P14 the same as that in a No.1 or No.4? I have a P14 which really looks to be unfired in terms of the amount of cosmoline on it, specifically on the feed ramps, in the action etc, the unmarked condition of the follower, locking lugs and barrel etc, but while the bore is shiny, unblemished, and the rifling extremely sharp, it doesn't seem as deep as that on my other Enfields.
