I ordered some as well and had a great range session. Here are some good loads to try:
76gr H-414 (or W 748) F-215primer (about 2560 fps, 24" barrel Mod 70)
OR 74gr RL-15 and F-210 primers (a cleaner load)

A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
