QuickLOAD's listed case water overflow capacity is about 3 grains less than .30-06, so it's not surprising it doesn't like quite as much powder.

Weigh one of your fired cases and then fill it level to the mouth (no meniscus) with water and weigh it again and record the weight difference. A lot of .30-06 out of production chambers seems to come out in the range of 69-71 grains of water capacity by that method, to give you a comparison to make.
