I am in the process of getting together some stuff to slug my .357 magnum bore as well as measure the cylinder throats with an eye to open them a little.
So far, my ruger, security six leads a lot with some hard cast low power loads but not with magnum loads launching the same bullet. The prevailing opinion hereabouts was that the cylinder throats were smaller than the bore. This sized bullets smallish as they launched from the cylinder and, when the loads were low power, kept them from obturating to fit the bore when they were traveling down the barrel.
So far, I've only got two of the five pin gauges I ordered to measure the cylinder throats. Arrived are the .356 and .358. The .356 fits all cylinder throats, the .358 fits none of them.
I have not yet slugged the bore but have some suitable fishing weights on order from beartooth bullets.
Looking at the brownells catalog, specifically at the manson revolver cylinder throat reamer, I notice that the .357 reamer cuts throats to .358. This means it would cut steel from all my cylinder throats.
I will do this, with the reamer and the pilot pack, if I find the bore larger than my cylinder throats.
ANYWAY... my questions after all that jaw-boning are: Has anybody used the Manson Cylinder Throat Reamers? Opinions? And do they have a flat on the shank? or will I have to find some kind of rare T-handle with a chuck that can take round shanks?
