I’ve been curious about the benefits of a 223 AI cartridge over a standard 223. I’m interested in reloading 69-77 weight bullets, and @ most would do a 26” barrel. To add context, the powders I have are BL-C2, CFE 223, & XBR 8028. I’ve read that you can push 3000fps in the 77gr class bullets with this AI. Any chance it can go hotter? Say 3050-3100?? Thanks, Isaac

I got an average of 2949 with a regular .223 77gr Sierra TMK sitting over 25.5 gr of Shooters World Precision powder
Depends upon a magnitude of factors. I’d be looking primarily for pressure signs immediately when pushing the limit and also be knowledgeable about temperature affects that play into load workup. I.e. don’t do load data in winter with super high charges and expect no pressure signs in summer if you received non in winter.
