The 77-grain open tip match (OTM) has a stellar reputation among end users. The MK262 load is a favorite among military users, and similar loadings are popular in service rifle competitions. The quintessential 77-grain 5.56 load is the Black Hills MK262 Mod 1. However, it can be hard to find and fairly expensive when it is available. Other manufacturers produce similar loads but the prices tend to be north of $1/round.

AAC currently has their 77-grain load listed at $14.99 for a 20-round box. That is a very competitive price for ammunition with a name-brand Sierra match bullet. It is available for purchase as of writing via Palmetto State Armory, which now controls the AAC brand. Hopefully, they can keep pace with demand.
