GENTLEMEN . . . I am running a thread in the rimfire area about shooting a 'Peep & globe'...in that thread I had shown a picture of my crown on a Savage MKII FVT, .22lr.
We were discussing the bore condition when one of the fellas mentioned that he thought the crown might be the culprit for creating shot dispersion.
I am reading this book to find out about the crown this gunsmith does on his work but haven't found an answer yet as there's no chapter on crowns...this book is a collection of papers and articles that Bill Calfee has written over about a 20 year span and then later published in book form.
All I have discovered thus far is that a taper like this keeps the live center part of the lathe better engauged with the barrel on the lathe. He didn't go on in that paper to say what he does later with the crown.
I'm sure to find it somewhere in this 721 page book but...I thought perhaps one of you might comment on this subject of 'CROWNS' in a lead shooting barrel like the .22lr.
I don't know my butt from my elbows about machine work or gunsmithing and would appreciate you fellas giving me a good education along with the folks following that thread I'm running.
Thanks very much . . . charlie
