Re: custom ear plugs
I had a pair made up at the local gun show...
I've still not made up my mind yet. They're easier to insert than traditional squishy foam plugs, but somewhat more difficult than the baffled semi-rigid rubber earplugs. On the other hand, they tend to stay in better than any traditional conically-shaped plug.
Who knows what the noise reduction levels are, but I've found them to make it noticeably more difficult to carry on spoken conversation than traditional plugs (good or bad, depending on who you're around I suppose). On the other hand, I had pronounced ringing from my strong-side ear when shooting my .308 RFB; the vibration transmitted right through the receiver into my ear.
Honestly, finding good hearing protection seems like a never-ending quest. I've tried and trashed so many pairs of earplugs, earmuffs, electronic ears, etc...and I've never found anything that satisfied me perfectly. Muffs suck for rifle shooting, but if built well and worn properly they seem to provide the best protection. Earplug fit seems to me to be a matter of luck whether a particular brand works for you or not...Wal-Mart used to carry a cheap Peltor or Winchester-brand corded earplug set for $2 that worked beautifully, and then I lost my last pair and Wally-World stopped carrying them. I picked up a really nice free pair at SWAT Round-Up from a company that was handing them out..and then promptly lost the plastic baggie with the product name on it, never to learn again who they are.
