I've never found it to be "hotter" than the manuals say. Ejector marks are not a good measure of pressure at any time in my book. I'm not saying it can't happen that it could be pretty hot but I've gone through several lots and found it to be one of the most consistant powders I've ever bought.
For me my quickload program has predicted it "right on the money"....you may want to get someone to run some quickload info for you on your different cartridges.
