I have custom molded one of a kind ear pro that the gov buys for us but the damn things take a couple minutes to get seated correctly and hook up. by that time the shooting is prob already over with...
I have been shooting most of my fairly long life, and only started thinking about hearing protection the last few years. I can still hear pretty well. Bump in the night scenario, I am not worried about ear plugs.
OK, so ear pro..... I've worked in high noise environments all my working career, including the Army. I'm 66 years old and for most of that time "earpro" had not yet been invented. I do keep a couple pairs of those around the neck hard band attached rubbers things hanging on my rifle, if there is time. However, deaf is better than dead.
P.S. I'm already deaf as a stone except for the ringing and the voices...... the dammed voices.
Hearing loss generally shows up decades later. I can hear pretty well in a quiet environment, but noisy ones are iffy. I tell people my tweeters are blown since those ranges are the most affected. I don't own a MSR and our shotguns are in the safe. HD for me is a choice of handguns (I got one for each of ya).
