Legalapproach has got it right! Do yourself a favor and get yourself the noise attenuating earplugs. I use and reccomend these. I have shot on average 500 12ga rounds weekly on the skeet range as well as shooting my high powered hunting rifles several times a month for the past 2 decades. I have also flown the mighty T-37 Converter and the Herk both of which can be hard on the ears. Despite all of this I score top marks on my annual audiograms. Hearing protection...use it!!
Cheers,
