The ratings deal only with continuous noise.
So what the 101 db rating means is you can work presumably a normal work day in a 101db background noise environment and not exceed an approved level of exposure in that time provided the earmuffs fit correctly.
Firearms have an impulse noise and it is extremely difficult to measure with any sort of meaningful reliability.
I would suggest that, irrespective of any ratings, when exposed to repeated firearms noise you wear both ear plugs and earmuffs.
Unless of course you only value your hearing at $29.
I know from personal experience. I was once blessed with youth and it's attendant ignorance like so many others.
