AA load data question

[Dr. Lee]

I just got my Grendel reloading handbooks and was noticing AA start loads and max loads were, in some loads, only 2 or 3 tenths of a grain difference. That seems odd to me. Kind of a narrow span. Factory load data show loads with several grains difference. I am new to the Grendel but not to reloading. Anyone how why ?
Thanks,
Dr.

Hi Doc,

Not sure why they published data that way. I would apply common safe practice of backing off their max load by 10% and working up for your new Grendel. Same for the other loads listed in the Handbooks. Welcome to the Grendel world. Have fun.

thanks Rick, that's what I thought someone might say. I don't have a gun yet but I am learning as I go.

Hi Bill. I am glad to see that your move from Stargate Atlantis to North Carolina was successful. Say "Hi" to Rodney for me.
