Arlo_Dog said:I still don't see how this clears things up. 43 gr. powder does not equal 1/4 full case. It doesn't equal 1/2 full case as far as I can tell. Also, looking at the chart on IMR's page, starting loads for the 165 gr. bullet listed, (sierra SPBT) the starting load is the same. Something still doesn't add up.
