\"Quiet crowns\" - reducing percieved noise and ear damage?

With a growing interest in protecting my remaining hearing while hunting I have been told of "quiet crowning". 1-2 inches depth of wider than bullet crilling in the end of the barrel.

This effectively would form a sleeve and project the sound forward away from the shooter. Not unlike a muzzle break but pushing everthing forward

I have seen something similar on a .22lr that seemed to work.

Has anyone come across this sort of setup and was it effective?

Ideally I would use a sleeve over the end of my varmint rig and ear plugs to protect my delicate ears when out in th field -assuming it can be done legally in Australia

Re: \"Quiet crowns\" - reducing percieved noise and ear damage?

with a 22 it is called a bloop tube...an easier method might be to carry foam earplugs with you when you need to shoot.

Somehow I doubt this mod would make much difference...

Re: \"Quiet crowns\" - reducing percieved noise and ear damage?

Why not get a set of the electronic ear muffs that cut off the sound when it reaches a certain level. I have been using these and they work great. You can have a quiet converstion with a fellow shooter or hunter and when its time to shoot just pull the trigger and it blocks off any loud noise.

Keeps your ears warm as well in the cold.

Worth a look.

On a high powered rifle I would be worried about turbulance with the crowning method you discribed.

I've heard that those holland muzzle brakes really keep that noise down.

Re: \"Quiet crowns\" - reducing percieved noise and ear damage?

I have read somewhere that that type of crown was detrimental to the accuracy of the rife. I have also seen a guy with an 8mm Mauser he was playing around with that had basically a counterbore for a crown. It shot a one hole group. Goes to show you shouldn't believe everything you read I guess. I don't know if it made the rifle any quieter to the shooter or not.

DAVYD

There is such a thing and it does work (for perceived sound)

You see extreme examples of these on some assault rifles and machine guns.( they look like a funnel )

I personally dont like muzzle breaks so when at the range
I wear ear plugs (ear muffs get in my way).

When hunting I like the electronic ear plugs that chop
loud sounds like muzzle blast but allow you to hear normally

I cant hunt with ear plugs or ear muffs (cant hear) so the electronic ear plugs work great.

As others have said deep crowns CAN cause accuracy problems.

I like to crown .060 deep, cut away from bore 90o and then
11o out.

The 11 degree angle seems quieter and minimizes turbulence
as the bullet exits.

What ever you decide protect your ears. [img]/ubbthreads/images/graemlins/cool.gif[/img]
