Hey all. Getting ready to load some 308 shells. I’m using CCI 200 primers and Sierra 168 Matchking Match bullets. My old Sierra book lists 48.6grn in the Winchester 748 powder as the max load. I bought The Complete Reloading Manual for the 308 as I wanted to see the newer powders the old book didn’t list. This book lists the max 748 charge as 44.8grn of powder. The two books also show different loads for the same velocity. An example is 45.1grn in the old book versus 43.4grn in the new book for 2600 fps. Since I have 748 powder on hand, I had originally planned on using 47grn as a starting point. Well below max in one book but over max in the other. Since the new book arrived, I’m kinda at a loss at which data to go by. Has the 748 powder changed since Hodgen started making it or is this a liability issue? Any help would be appreciated.
