Yep, LOTS more of it. I find shooting with a muzzle brake absolutely requires double hearing protection (plugs and muffs). Didn't even like shooting it once without plugs when hunting and can't see spending the money on Walker's game ears or something similar, so I sold my 7-30 with a brake. Lots of stuff out there that you can handle without a brake, so I'm sticking with that.
