I'm kind of old school, I don't judge until I experience it myself.
I have only shot mono's for 40 years, have no problem with either Barnes nor Hammers. I do drop down in weight considerably. My 20" 7PRC shoots the 140 AH at 3300. Probably have 15 different rifles that shoot mono's, majority are Barnes, but have switched a few to Hammers. One load that kind of surprised me was my XP100 7BR, switched to 67 Stone Hammers, 3200 fps out of a 15" barrel. Haven't shot anything with it yet, but I am sure it will do just fine.
