I have trouble hearing a steel hit with plugs, any recommendations for electronic muffs with a fast enough revovery on the sound? Thanks

This is for a non USPSA match , my question is will there be a difference between 100 grain and 124 grain 9mm bullets ability to take down poppers if the power factors are the same or will the heavier bullet have a better chance of taking them down? I'm hitting the Knob Creek pistol match this coming weekend and they set their poppers really light but want to make sure if I use the 100 grainers they will still take them down. Thanks Ajax
