Reloading the revolver is an exercise in precision. Trying to insert small uniformly sized cases into exactly measured charge holes is a task onto itself. Add stress and the task becomes a challenge. One of the things that will slow down reloading the revolver is the outer edge of the cartridge’s shoulder contacting the inner edges of the cylinder’s charge hole. When using a five or six round speed loader the shoulder of any single round can prevent the whole set being reloaded into the cylinder.
A simple solution is to slightly bevel or chamfer the edges of the cylinder’s charge holes. Removing just enough of the inner edge of the charge holes to give them a funnel shape in microcosm and will go a long way in speeding up reloads. The edges of the charge holes need to be beveled only slightly and the work should be performed only by a competent gunsmith. A skilled gunsmith will know exactly how much material to remove and at what angle the chamfer should be made. He will also know how much material to leave because if the chamfering is cut to larger it will leave insufficient material at the mouth of the charge hole to support the rim.
A snub with a properly chamfered cylinder is easier to reload and could well turn out to be a life saver. Note that if you own a titanium cylinder snub you have to spend more time either practicing your reloads or your second snub draw skills as chamfering a titanium cylinder is a difficult if not an impossible task.
