Double-duty reamers lengthen short chambers to modern
standard or magnum lengths and cut the new long forcing cone at
the same time - OR - will cut a long forcing cone without
lengthening the chamber for the gunsmith seeking improved
shooting performance for his customer. Flute placement, relief and
angle are designed to give the best possible results on all types of
barrel steel (except on chrome lined barrels, of course!). The
1½" long (approximately) forcing cone created is
performance proven to give optimum results in any length
chamber. (For complete instructions see below our detailed,
illustrated
booklet, Measuring and Rechambering Shotgun
Chambers.)
Reamers are ground exclusively for us from
special, select tool steel by one of the oldest and most respected
manufacturers of reamers in the United States. Quality and
performance is 100% guaranteed. Plus, the hex-drive permits use
of a socket and T-handle when tap handles will not operate. Lathe
setup not required.
