I find this reloading topic very interesting. I enjoy reading from those that are engaged in this hobby. Some day I am going to be forced into this area, if I continue to seek out weapons for which ammo is scarce or high priced or in need of softening.
I think the truth is, from my readings here and there, that there may be as many or more who load soft as opposed to those that wildcat or load hot.
A lot of the games folks, ie, cowboy action and other of the modern handgun games tend to find soft loads which will still perform on the targets prepared for these games.
Accuracy buffs tend to look for loads, hot or mild, which give the best accuracy for the particular bullet of the day.
Some sports, bowling pins and such come to mind, and these may require hot loads, though I think caliber is more of the norm than the loads.
Just my observations though and still admitting that many just like to hot rod.
Blessings
