I was leanign that way as well, and then I saw a post that said avery was getting better velocity with 555.

Using QL presets they should be fairly close assuming a 24" barrel. Slight edge to N560 which appears to top out on load density before it tops out on pressure. N555 will work near the top end for pressure with a complete burn. If going shorter barrel, I would try N555.

I would try N555 first especially if you shoot suppressed. It's also very temp stable if that matters to you.
