Ruger and many other manufacturers of single action revolvers have
throat diameters that are too constrictive, causing excessive pressure,
erratic groups and heavy leading in the barrel when cast bullets are
used. Bullets passing through these overly constrictive throats are
swaged to a smaller, incorrect diameter for the barrel. The bullet
will not consistently enter the rifling in the same manner with each
shot, causing erratic groups.
What Reaming Accomplishes
Reaming the throats to the proper diameter allows
the bullet to enter the rifling exactly the same was with each shot,
promoting better groups. Cast bullets can be used with out the
How We Ream Cylinders
Itís easy to purchase a hand reamer and twist it
through each chamber. The problem with this method is that each
chamber will be a little different and the throat will have unequal
diameters at the beginning and the end due to the reamer wobbling in
the chamber. The shape of the chamber and the short throat makes it
impossible to get a precise ream by hand, even with a piloted reamer.
We ream the throats with very ridged set up on a
precision mill while flooding the hole with coolant. Each throat is
cut exactly the same to the precise dimension.
When we modify your cylinder, rest assured that each
throat is bored to the exact tolerances with virtually no variation
between each of the 6 throats.

Some cylinders do not require
reaming. If possible, measure the throat of your cylinder to ensure
the throat diameter is smaller than the final reamed diameter listed
above. If not possible, I measure them before reaming and if no
reaming is required, I will send it back for only the cost of
