Need recommendation on good external hearing protection (ear muffs). I also use ear plugs, but notice that any ear muff (Winchester, Silencio,etc.) only have a DBA reduction factor of 28/29. Is this the upper limit of reasonably priced hearing protectors? Please let me hear your personal experiences. Have recently joined an indoor range - much louder, of course, than shooting outdoors. And do not want to lose my hearing practicing my passion. Thanks in advance.
