Yes, campfire members never shoot handloads over what reloading manuals publish.
I'm sure there are some that do, just like there are risk takers in all sports. I've never done so, and see no reason to. The slight velocity gains are not worth the risk. If your max load is going too slow for you, buy a bigger round. Don't try to turn it into something it's not. Instead of trying to boost a 300 Win Mag to higher velocity/unsafe pressures, he would have been better served to go buy a 300 Weatherby, a 300 RUM, or a 30-378 Weatherby.
While it's true that all liberals are crazy people, not all crazy people are liberals.
