I had one installed on one of my 7mags back in '96 IIRC. I was crossing a snow covered clearcut in Idaho when a nice whitetail buck broke out across at about 300yds, spooked by a passing hunting rig going down a logging road. I pulled off a hail mary shot and was greeted with one of the loudest ear piercing ka-booms I've ever heard. Grabbed my ears in disgust and was even more disgusted when I learned I missed the buck. My ears rang for a couple days after that. I sold that rifle a year later, it sold quickly at a gunshow cause it looked kinda cool with that Gentry brake I guess.
