I’m looking at two different reamer prints for 6.5x47 Lapua. My question concerns the relative dimensions of the neck – the neck diameter at the neck-shoulder junction, and the neck diameter at the case mouth.
On the first print, the dimension at the neck-shoulder junction is 0.2933”, and the dimension at the case mouth is 0.2921”. Clearly a taper of 0.0012”.
On the second print, the dimensions are both 0.296”. No taper.
Why the taper? Why not the taper?
