Ive got a very nice Eldorado Gun Drill for sale, if anyone wants really
deep straight holes...

Certainly far better than drilling with twist drills, but I recall
watching
P.O. Ackley straightening barrels drilled that way too. :-)

St. Ackley never used an Eldorado gun drill G

You're most likely right. I think my point was that even gun drilled holes
aren't necessarily dead straight (what does that really mean?), but then
after turning the OD , you'd certainly have error to remove, even if the
barrel had been drilled what could be considered straight. My report of
watching him straighten barrels is the only part I recall, that and the fact
that it was all done with an overhead press and checked by sight. It's
been about 20 years. Hell, he died in '89. Time flies!
