The 2512's should shoot fine at 30"cut length with 100gr points, but they will be less durable than 3-71 ACC's at the same length. They will also exhibit more wind drag than the slimmer ACC's.
You could also choose an appropriately sized Beeman ICS shaft. It will approximate the ACC in performance, but will cost less.
