What does the article have to do with WEARING OUT a bore. Again you copy and paste some garbage from a source who is questionable at best.

Rattle down a bore?...come on thats nonsense and if you knew anything about conicals you would know there are many of them that are far from undersized. Such as Great Plains, Maxi balls and REALS. Its far from the "norm" for conicals to be slip fit.

Here is a great PRO for a lead conical.....No short starter needed even if its .002 over land size....How do i know....I actually do it....Not just copy and paste something ive read. When you actually DO something its easier to spot the BS posted on the net.
