JJD, I have one on my 7mmRUM. I can shoot it without the brake but with all the reloading/shooting I do, it really makes a difference. They are loud for sure. You can either wear ear plugs/muffs as I do. When I'm deer hunting out of a box blind or treestand, I wear my walker's quad muffs for hearing protection and to hear the deer/wildlife better. I use them at work also as my hearing was getting bad before I purchased the RUM. I know not everybody would want to spend the extra money on the game ears but it worked out for me. Because I work in construction, I can write off the cost. hope that helps.

I shot a 7mm mag with one one time. One time = one shot! That was enought for me!

I changed out the flash hider on my M1A to a muzzel break and I found my follow up shot were a lot quicker, and reduced recoil to about the same as my SKS. I like them.
Now if you get an adjustable one you can tune the harmonics of your barrel so that you get tighter groups. Just a thought.
F.K.

Love mine on my .340 Weatherby! ...LOUD is correctamundo! But, really did wonders to reduce the recoil on the big magnum!

I have a removable one on my 340 Weatherby and love it for shooting off the bench but I will take it off when hunting. I was working up some new loads this past summer with it and did not have the brake on and afterwards I could really feel it. I also have a barrel for my Contender in 7-30 Waters and wouldn't be with out it on it. It does however drops the muzzle velocity down 200 fps on the Contender. I haven't checked the Weatherby for any variation yet.

Don,

Was the noise the issue?

What did you say? I've never heard a shound that loud in my like befor and I'm already darn near deaf!

OMG! No kidding! The first hunt with my .340 I had ringing in my ear for a month! NOT GOOD!

The only other thing that was ever that loud was when I was on the firing line and standing next to an M1 Abrams, and had no idea that it was a live range... KABOOM!

Needless to say the coffee I was bring my 1stSgt was in the air real quick!

That is what I like about the one that I have on my .340 Weatherby. You can remove it for hunting or put it on for use on the bench or sighting in. I do know of some guides that don't like to take hunters with rifles that have brakes on them just because of the noise off to the side factor.

Critter,
Do they thread the barrel for the removable brake?
Does taking it on and off change the point of impact as a result of change in barrel whip like the BOSS system?

Don,
My hearing aids will be here just after the first of the year, no joke
Noise factor is a serious consideration. I can aford a sore shoulder, but can hardly aford any more hearing loss.

All,
Thanks for the input.
