25-06 Ackley
There is a distinct lack of data around for most of Ackleys cartridges. As has already been stated some of the manufacturers data is basically identical to the standard case data so is not much help. Some of the data obtained off the net is very, very hot loads. With the standad cartridges you can use deformation of primers as an indication that you need to reduce slightly but because of reduced body taper you should not use this with Ackleys cartridges. For example reduced body taper should mean less bolt thrust if you see what I am getting at.
I guess a chronograph and much caution is the best advice.
I know that with my 22-250AI I can put 55 grain Nosler BT's down the range at 4200ft per second on the chrony and have no signs of excess pressure but the velocity itself tells me that the load is getting pretty hot.
