Just for the record, I too hated brakes until I reached eighty and a serious bout of arthritis. To keep shooting what I like, I had to take some practical steps: including Mag-na- Porting on my .458 (it came with that), reduced loads and a bit of extra overall weight in the rifles. Protection of hearing is certainly a priority, but so is one's eyes, bones, ligiments and muscles.
And I'm not disagreeing with RinB - whom I genuinely appreciate.
And also for the record, the 9.3 x 62 is one of my all-time favourites.
