I purchased one of the Lee 113 grain RNFC bullet molds (C309-113-F). I have cast up some bullets with it using straight WW material and then I have heat treated them to attain a BHN of around 20.1 according to my Lee hardness tester. These were sized at .311 before the heat treatment and they do measure .311. I'm looking for an accurate flat shooting load out to 100 yards if possible with this bullet. I know some of you have reported accuracy problems with these bullets at this range but I thought I would give them a try. I'm using 2400 as my powder of choice for these loads. They are crimped using the LFCD as this bullet has no crimp groove. Last time out the loads at around 20 grains looked the most promising for accuracy. I have some loaded up with 20.2, 20.4, and 20.6 grains of 2400 to try out in the morning. I may run a few over the chronograph to check the velocity. These will be shot from my 336C with the micro-groove barrel. I have enjoyed all of the input on this thread and hope all who have contributed to it to keep us updated on your results.
