Need some recommendations on ear protection. Shoot only at an 100 yd.indoor range. (Savage MK II). Have molded ear plugs that are not adequate when others are shooting .50,.308 and other high caliber rifles. Want to purchase muffs, but with all the brands and types, it is confusing. Range has loaner muffs, but do not like to put on muffs worn by others. Am concerned about ear damage and have left on some occasions when the noise becomes too great. Would like to hear what some of you are using to help muffle the noise. Appreciate.
