Has anyone loaded the Sierra 100 gr. HP ( 1710 ) in the Grendel? I would appreciate any loading data you have tried. I have W748, Benchmark, Varget, 8208 XBC, and H 335 as my choices for powders. I am open for any advice here. OAL for the AA upper would be appreciated as well.
Thanking everyone in advance.
