REPAIRING SHOTGUN BARRELS
There are times when something gets into the end of the shotgun barrel that causes an obstruction.
When fired there may be a bulge formed, or the end is blown off.
To repair such a barrel, there are three choices:
- Cut off the barrel and shoot as is.
- Install some type of adjustable choke.
- Add an extension to the barrel that has the choke in it already.
To do the latter, you will need a barrel that is as big on the OD as the old barrel, and one that has the
choke that you want.
A lathe will be necessary to do this job, with at least a 36" distance between the centers. You will need
two centers that are big enough to center the bore, and one a live center.
Cut off the barrel right behind the bulge, and true up the end in the lathe. A steady rest will be needed to
hold the barrel unless the bore of the lathe is large enough to hold the barrel. When the barrel end is
trued, center the barrel, and set up the steady rest about 2 inches from the cut off end of the barrel.
Once it is set up, you will bore the inside of the barrel 1/2 of it thickness, and 3/4" deep into the bore.
Measure the ID very carefully so when you turn a shoulder on the extension barrel, as it will need to be a
very close fit.
The shoulder angle has to be very accurate, so the fit between the two barrels will be exact. The length
