For muzzle blast, use ear protection. Ear plugs at least, maybe something better.
You could wear a special shooting coat with an absorber pad. Alternately, you could put a recoil pad on the .30-30.
I have considered the use of earplugs but wonder if I would have time to stick them in when the shot presents itself. I am not hunting with plugs in all day. Of course there are electronic ones, but rather expensive.
I am more concerned about blast than recoil, of course the less the recoil the better.
