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 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.
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.
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.
Here is an inexpenive and effective deer feeder I made recently.
No batteries to go dead, no hoisting it up in the tree, plenty of capacity, very easy to fill - so far, I love it.
I have made two of these and they are easy to build.
An empty 55 gallon drum, some 2x4's, some PVC tubing and fittings, a little bit of hardware and some paint - and you are ready to go.
I designed it so you can stand on the lower rung and fill it - the top is about 6.5 feet above the ground.
It holds about 375...
