The chart I use most is Hodgdon's. Burn rates are established by the "Closed Bomb" test. All powders are tested in the same size vessel, so they very often change in burn rate specific to the cartridge you're loading. You don't want to load TiteGroup with any other data than that for TiteGroup and it can be touchy and pressure spike when Max. Charges are used.
TiteGroup is listed at 14 while AA#2 is at 25. Definitely not a good choice as far as any chargeweight or pressure comparisons. AA#2 is very similar in burn rate to ZIP and W231. In any case, it's a more forgiving powder.
