The 260 AI is not in the QL database. The 6.5x284 is 6.5x284 Norma
Using defaults for everything other than the specs you gave and choosing the 130 Accubond as the common bullet:
6.5x284 Norma - QL chose Ramshot Big Boy 98.1% fill 2831 fps
260 Rem - QL chose Ramshot Hunter 98% fill 2687 fps
Neither are max loads ~90% but they give a reasonable comparison.
In my opinion for either of these to work well other parameters need to be modified.
