I have been using, or trying to use, the lee 100 gr. RN #311-100-2r in my .32 H&R Single Six with terrible results. The problem I believe is fit. My cylinder is .3105 my barrel is .310. The mold seems to be working for my dad so I don't wanna mess with it, so I'm in the market for a new mold. I have been looking at a mold by Lyman #313249 I am going to buy another sizer in .312 the last one I bought was a .314. I'm really trying to get away with shooting straight wheel weights if I can. Does anyone have any recomendations concerning this caliber?
