I email Wilson Combat about specs of their .458 can. Below I their response
Neil,
The .458 can is still on the drawing board. I’m sure that there will be a video for it, it is just too cool not to.
As far as db reduction, don’t drink the cool-aid. There are no industry standards to make everyone conduct the reduction measurements the same way with the same equipment.
Decibel reduction is subjective and can be manipulated by the type, angle and distance of the microphone, the type and quality of the sound measuring device, and the environment and atmospherics of where the test is made (indoors vs. outdoors, baffled walls or bare, cloudy or clear, windy or still.)
Without using numbers to describe performance, our can makes a 5.56 sound about like a .22 Mag. I can’t wait to hear what it does with the .458.
Best Regards,
