What you should do is start at the minimum load and work up to find a accurate load that is not excessive pressure. Do NOT start at the minimum load and work down!
They're not minimum loads, just convenient starting points. There's no reason you can't work down from the start loads if you want to, not everybody wants or needs maximum pressure.
ADI's AR2208 data for 55gn jacketed bullets is 25.5gn up to a max of 27.5gn, but with a short 2.200" cartridge length. With the 52gn and 53gn jacketed bullets it's 24.0gn to 27.0gn which makes little sense.
24.6gn of AR2208 behind 55gn jacketed bullets is certainly in the right ballpark. If you're seating long then pressures will be even lower.
