Re: 6.5 WSM Whacks Another One
So mine may not be the EXACT ones sold by Len on this site as they were bought at the NRA dinner auction. My first impressions were:
These things are small!
I put the batteries in and... are they working? (lesson get the batteries positioned correctly)
The directions also help in selecting the correct rubber "plug" part (i highly recommend the orange ones because if you drop them in grass you may never find them.)
the earplugs were first tried while shooting a hot loaded 26" 25-06. They work better than nothing but not as good as a good set of foam plugs. The cutoff of blast is imperceptible but there is no ringing in my ears, so it must work. The bullet impact is very easy to hear since the transmission of sound begins quickly after blast.
My second test was with a Lone Eagle 15" 30-06 with radial muzzle break- conclusion: these things can't reduce enough noise to compensate for such a compensated pistol.
I know Len tested the "industrial grade" versions, so maybe they have a better noise reduction rating than the ones I have.
Final thought- its better than hunting without plugs but if you're shooting a short barrel/ high blast/ braked rifle they might not be enough.
Learning every day.
