Not really. Doubling up with plugs and muffs assures your hearing always has some protection.belt and suspenders here.
When wearing muffs, often times the ear pad seal is not fully engaged. There may be gaps in the protection due to things like safety glasses, long hair, cheek weld on stock, etc. Wearing plugs protects your hearing when these things occur. IMHO, my hearing will be better off in the long run if I double up protection.
