I have been casting for a couple years with success, using lee molds in 30-30 (150gr .309 LFN), 45-70 (405gr .457 LFN), 32SWL (90gr .314), and 32 H&R mag using the same mold. I am using wheel weights for lead. Worked with 9mm (124 gr LFN TL) with no success and it has been put on the back burner for now, until I can try a different mold.
So thinking revolvers would be easier with cast bullets, I bought a SP101 in 327 and loaded a few Hornady .312 85gr and 100gr XTP with ok results, but still working with them. When I tried the Lee 90gr mold with the 327 I am getting excessive leading no matter what speed I push them. Checked the 327 throats and bore with calipers and to my surprise .308 throats and .309 bore.
Is this normal for 327's or do I have an odd ball? .308 seems excessive even for .312 jacketed much less .314 lead. Even the bore seems a bit small but maybe that's normal? Should I get a 30 carbine mold and work from there or should I have the throats reamed by a gun smith? Would Ruger say this is in spec?
What are you folks getting with your 327 revolvers?
