In case you didn't see them, Howard Leight also makes a 33dB earplug. I use both the Leightning earmuffs and earplugs when shooting the big monsters with muzzle brakes
Makes the whole experience much more comfortable. Probably increases accuracy too by reducing flinching (we don't do that do we).
I love this sport and want to keep my hearing too.
Remember that 3dB is doubling the noise level. Most "good" earmuffs are rated at 29dB. The leightning rated at 31dB reduces our exposure to noise by about 50%. Good stuff.
