Maybe I am not looking in the right place but I searched on here as well as the internet and did not see very much data on this subject.
This is my plan. Alliant's website lists the following information for RL17 and 300 WSM. Speer 180 Grain BTSP, Federal Case, Barrel Length 24", Fed 215 primer, and 66 grains of RL17 for 3082 fps. This is the only manufacturer load data I have been able to find. In the fine print before entering their reloading data page they state that all loads listed are max and you need to subtract 10% and work up.
In my case, working up is going to be new to me and reading through here and other places I have learned some of the things to look for. Mainly, cratered primers, ejector marks on brass, and snug bolt lift. Also, an increase in powder weight with no increase in fps.
Here are the loads I just finished using 180 grain accubonds with winchester brass and CCI 250 primers. Barrel length is the same at 24". I plan on shooting these over a chronograph and checking the cases very carefully after each shot. Anyone see any problems with the plan?
60 grains 5 rounds
62 grains 3 rounds
64 grains 3 rounds
65 grains 5 rounds
