PSA has a deal on .308 Federal Sierra Matchkings in 168 grain and 175 grain right now. I’d like to pick up a few hundred rounds while they are on sale but don’t have a lot of experience with either. Just starting to venture into target shooting.

For ya’ll that shoot long-range, all things being equal, which would you prefer? I have a .308 precision rifle with a 20” barrel that I haven’t shot yet. I doubt I’ll see many opportunities past 500 yards but if one is generally better I’d appreciate the input.
