When looking at reloading manuals. Which do you go off of for starting loads? im shooting the 160 grain McGuire copper rose. 3.400” to the lands.
And loading STABALL HD. Im looking For the starting load but the max loads are off by 3.6 grains.. barnes shows max compressed load at 73.9compressed grains and hodgdon showing max 70.8 grains with only 5 thousands difference in coal. Anybody have a load that works for them using this combo?
