Yes, they are rare. It also depends on were you train, if in the company of Olympic lifters or Strongmen, you probably have a better chance of seeing big presses. Powerlifting gyms, it depends.
I'm still sticking by anything better than BW for your average lifter. Something to consider is that huge pressers in strict style(Hepburn, Anderson, etc....) were only pressing about 120-125% of bodyweight for World records.
.
The double layback style of the 50's- early 70's boosted that to about 140% of bodyweight for the biggest record holders.
The one sticky wicket is the lighter classes, they are usually around 150-170% of bodyweight.
As for a real Military press, I don't know, the feet together rule kills poundages.
In talking with, and observing overhead strong lifters, most of their overheads are 70%-75 of their bench press at the top end.
