OK, I am going out on a limb and will cop flack for this post but whatever
I hate, any and all porting, I hate cans and suppressors unless used in built up areas or required by law and I hate anything on my ears when I am hunting.
OK there it is I have said it.
If you feel that the few shots a day when rifle hunting will affect your hearing, your call not my problem. That said you then have the same hunters when waterfowl hunting shooting tens if not more than a hundred (12 gauge) shots in a session and doing the same for several days during a season: season after season without protection and without any major detriment or hearing loss.
Is my hearing 100%, no, but then again neither is my mothers who has never fired a rifle or been hunting in her entire life. We all get older, and things wear out.
There is such a thing as industrial deafness when constant exposure to loud noise does damage over time and in the instance of extreme noise may damage instantly, but this is not what is happening in the field. Under a structure at the range is a different story and hearing protection is a must.
I prefer to have my ears uncovered so I can hear the natural sounds of the bush and more importantly the DIRECTION and intensity of those sounds. Something that I believe is lacking with electronic hearing suppressors or devices. A market has been created and retailers will exploit this to the best of their ability.
That's OK just not for me in the field where I may fire one single shot for the entire day.
PS. I am going goose shooting this afternoon and will hopefully fire many shots without any hearing protection and my ears will be fine. Although I have been to music events and concerts where my ears were buzzing afterwards. More damage done there methinks.
