Lengthening the forcing cone area decreases pellet deformation and felt recoil for a dramatic improvement in pattern density, shooting comfort and overall shotgun performance. Custom-made reamers with five, spiral flutes increase the cutting surface area for a smooth, chatter-free cut on all types of barrel steel. Do not use on chrome lined bores. Hex-drive shank allows the use of a standard square drive socket and T-handle.
SPECS: Tool steel, five flute, spiral cut, 6" (15cm) long, 1" (2.5cm) long hex section. Hex-drive size listed in chart.

Excellent tool(24/12/2009)
Used on Rem 1100, Winchester Select Energy Sporting, and Ithaca 37 barrels so far with perfect results. Use in conjuction with Flexhone to do final polish. This reamer is top of the line.
nice tool(28/01/2018)
Reamer works great, I used a 3/8 drive ratchet with 1/2 socket to turn the tool. Barrel vertical in barrel vise lots of cutting oil and clean chips off tool often and easy enough to do. I used a chamber gauge , to know the depth i was cutting, and was able to lengthen chamber with this tool as well. Did two barrels so far Winchester 97 and model 12 with a nickel barrel. I sanded and polished the forcing cones after lengthening and the results look like it was done from the factory.
