As I have gone down this path with a number of sixgunners who have troublesome sixguns, I have had to make clear any number of times, to end up with a trouble free lead bullet shooting sixgun correcting the cylinder throats is only the first step. In some cases the throats cannot be corrected because they are already too big, so the size of the bullet you are shooting needs to be larger than standard. I have ended up guiding some guys through the step by step process that follows beyond correcting the throats in order to get their sixgun right. So in short, helping you with a sixgun that is leading is what I am here to do. Do not suffer in silence, send me a PM. I will help you even if you do not hire me to do any work.
For you 32 guys and others, I have a bit of news. I now have what I feel is the ideal reamer to correct undersize throats in the various 32s. Ruger Single Six 32s will almost always have .309"-310" throats. The bore is larger at .312". This isn't going to work. Your cast bullet will not have proper purchase as it travels down the bore. This is also the main
source of your leading. Even if you shoot jacketed, you are beating up your primer pockets because you are sizing down your .312" bullet to .309" as it exits the case (pressure has to go somewhere) and again, that 32 that shoots 1 1/2" at 25 yards may well be much more accurate if that jacketed bullet could "grab" the rifling like it should. Ruger Buckeye 32s are also as a rule too small for cast. These throats need to be corrected to shoot a .313"+ bullet or at least .001" over bore (.312") size. Sometimes the throats in a given cylinder will vary in size. To address this, I have a sets of pilots in 1/2 thou increments to keep the reamer dead center. I try to keep this job at no more than 55 per cylinder plus postage. I have not measured nearly enough Smiths or others to make generalized statements as to diameter however, if you are in doubt, I will measure both your cylinder throats and or your cast bullets with pin gauges and a micrometer at no charge except return postage. Now, every Ruger Single Seven I measured has shown .314" throats. What you need here is a cast bullet at least .3135" or so. Too small of a cast bullet is just as bad because all the lube will blow out of the lube groove when the bullets leaves the case. Dry bullets will lead. Let me know if you need my help.
Additionally, I am set up to correct 45 caliber throats and am in the process of setting up to do 40, 41, and 44 calibers as well. Let me know if you need help or if you are having a leading issue. fermin
