On the recommendation of folks here and reviews at snipershide I ordered 500rds of Southwest Ammo's 77gr. It gets delivered tomorrow though so I won't have any results to share for a while. I've had good luck with Black Hills (68, 69, and 77gr), Corbon (77gr), and Asym (70gr) but not in large amounts and I'm still not good enough at distance to take full advantage.
Before you suggest that licensing, background checks, or other restrictions for the 2nd Amendment are reasonable... Apply those same ideas to the 1st and 4th Amendments. Then tell me how reasonable they are.
