You will need to increase the amount of effect due to the higher rez.
Essentially there are more pixels per inch at 300dpi than at 72dpi, so if you set the filter for a 10 pixel feather t will have a greater effewct at 72 than 300.
A simple way of seeing this is to open two images, one at 72dpi, the other at 300 dpi. select a paintbrush and look at the are it effects on the 72dpi image, then do the same to the 300dpi. The paintbrush will affet the 72 to a greater degree than the 300.
