Ran across a video where the poster was talking about an enfield of his and mentioned oblate land erosion where the corner of each rifling land was worn away due to the pressure of the bullets rotation. Curious if this effect extends throughout the entire bbl or not. My bbl slug looks decent with lands and grooves even if they only mic at .001- .0015 deep but looking at my rifle’s muzzle you can see where there is a corner on one side of the land but the other side kinda disappears until the corner of the next land. I’ve never heard of this before but my enfield dates from 1942 and who knows how many rounds it’s fired. I would be willing to cut the bbl down if it would give me a better bbl. Thoughts?
