I´m not an avid reloader--not by a long shot. That said I´ve done some reloading for 357 using 2400. It is the only powder available for Magnum here, so any suggestions with other powders i.e. H110 are out of context. So, I´ve done 158 gr. jacketed soft points and hollow points with 12.5gr. 2400 for my M66 2.5" with great results. I´ve also done 125 gr. bullets with 16 gr. 2400 with great results on same gun. I wanted to try a light load for the 340 PD and did 5 each with 158 gr. bullet and 12 gr. 2400, and 125 gr. bullet and 14 gr. 2400. I have never gone down this low even though the Hornady newest manual OK´s even lower loads. Can the more experienced guys here advice me on what to expect out of these loads? Do you consider them dangerously low ? I noticed some unburnt powder on the previous loads on the 2.5" M66 and I was wondering if a lower load would solve this problem. Oh and BTW, the primers used are CCI 550 small magnum. Extra care has been taken on these cartridges, once fired nickel brass, very clean primer pocket and case, very well inserted primer, powder measurement carefully digitally weighed and visually inspected afterwards for uniformity, and good crimp.
