First you need a cleaning rod that rotates
easily.
Place a cleaning jag on the cleaning rod.
With a cleaning patch over the jag, insert the rod a
few inches into the barrel. Put a mark on the rod
even with the end of the muzzle (tape really works
well for this).
Put a small mark on the end of the cleaning rod near
the handle.
Push the cleaning rod down the barrel until the mark
near the end of the rod makes one complete
revolution. Then stop.
Place another piece of tape on the rod even with the
end of the muzzle.
Withdraw rod and measure the distance between the
first mark you made at the muzzle and the second mark
you made at the muzzle and you have the
twist rate of your barrel!
If you measure 10 inches then your Rate of Twist or Pitch is 1:10 meaning 1 revolution/10 inches. |
