ive been shooting cast bullets for a few years now, and shoot mostly ruger blackhawks. I try to match my throats and bore size to my load etc,etc, i have some pretty accurate loads for them,but i recently (finally) bought a single-six in .32 mag. Upon measuring this thing it became apparent that the throat-bore size was way out of whack.Throats are .309 and bore is .3137, i never figured this thing wouls shoot...........upon trying it, the 85 gr. federal factory loads shot inside 2 inches ( scrubbed the copper out and will never shoot any again!) loaded up the empties with 4 grs. unique and half was a 94 gr. lee round nose and the other half was a lyman 311316gc, sized them 311 and you cant amagine how this thing shoots! using these guessed at loads,it shoots an easy 1 inch group (25 yards) and cant wait to fine tune it! Why i am confused is because this thing shouldnt shoot this well,, how can it?? it didnt seem to lead hardly at all, which i was sure it would because of the big bore size. the 4gr.-unique with 311316 (117grains) does seem pretty hot and probaly will tone this down next time!!! This thing is easily the most accurate hand gun i own! have heard that all these .32 rugers shoot well. Do they all seem to have the small throats? thanks,mark
