Well when I was teaching myself to shoot using a suppressed 22lr with 36gr subs I found myself in the next Bay to a 338 Lapua Magnum sporting a brake. So I had to contend with the noise, blast and chest thumping at random unpredictable moments. Certainly taught me to concentrate on what I was doing. Don't think it did me any harm. Made sure I had earplugs and earmuffs.
