Is it at all practical to consider enlarging the initial section of a 224 bore (say 219 actual) to 308 (.300) so that I can use a piloted counter bore that I already own (made for .300)? If so, what would be the best way to do it accurately?
After its all done, that section of bore get oblitered when I predrill it and use a boring bar to straighten it. So it does no harm as far as I can see to bore it out to .300 to allow the piloted counterbore to be used. But how to do it reasonably accurately?
(EDIT: This is all work at the muzzle using a PTG bolt nose counterbore
.705 Counterbore Without Step - Pacific Tool and Gauge
made for roughly .300 and up pilots)
