    Right on!
    I've had my ear drums blown out already and the 'sissy slots' on any rifle is terrible for what ever hearing I have left. I refuse to even be at the range with another rifle in the general area. And yes that's with me wearing plugs and muffs.

    I really have to disagree. A well constructed break, such as the Vais break, will not increase the noise level or blast.
    There are many others as well. If anyone has ever been to the PA 1000yd range in Williamsport PA, they'd see every rifle at the bench fitted with a break. I shoot next to others whose rifles are fitted with breaks all the time and never had an issue with it. Back to the topic of the .460...the Weatherby break, although very effective is without question extremely loud. But, again there are breaks out there that DO NOT notably increase the decibel level or blast.

    Can you show me the difference between these two. Pictures?

    Unfortunately, I have been trained to avoid them through painful experience. If there is something I can direct MB lovers toward to save my ears I would be appreciative. Thanks

    Here you go.

    Notice the holes on the Vais are much smaller and are bored with a forward angle to divert the blast forward.

    Actually a Vais brake does increase the noise level and blast markedly, just not for the shooter. It's just physics. It is quieter than a Barret 50 Tank type brake, but it also reduces recoil less.

    Here's a quote from the VAIS FAQ page:

    "Function


    Q. How much recoil reduction can I expect with a Vais brake?

    A. Our Vais brake is very efficient at recoil reduction. Exact percentages for recoil reduction cannot be listed for each caliber as it varies depending on bullet weight, barrel length, weight of the rifle, and in some cases even the powder used. Recoil reduction of up to 50% is common with the large 7mm and 300 magnums. On rifles such as the 270 and 30-06 recoil reduction of 40% is common. The reason for the difference is the magnums have a much larger muzzle blast and more energy for the brake to work with to reduce recoil. Big bore rifles such as the 375 and 458 are harder to tame down for two reasons. The heavier bullets produce more recoil and the larger bores burn the powder faster. This leaves less muzzle blast for the brake to reduce recoil. Average reduction for these calibers is 30% to 35%.



    Q. How does a muzzle brake work?

    A. A muzzle brake is designed to capture as much of the energy contained in the muzzle blast as possible. The brake converts some of this energy into a forward thrust which counteracts some of the rifles recoil.



    Q. What makes the Vais brake quieter than other brakes?

    A. Our Vais brake has eight small holes drilled from the muzzle of the brake. These holes are drilled through all of the cross ports and terminate in a small expansion chamber just ahead of the barrel muzzle. This configuration very effectively vents most of the noise and concussion away from the shooter."


    So the point is are you just concerned with yourself (you hunt alone?) or are you concerned about hunting companions, PHs, guides, trackers as well and how do they feel about it?

    Thanks.

    I'll get some ear protection and see if I can note the different types at a rifle range.

    I am around shotgun most and with them it appears to make no difference how the holes were made; drilling or laser. They all bark at the other shooters on stand beside them.

    I'm not sure why you're comparing a Barret type break to the Vais...they don't even look the same. Also, how are you concluding that the Vais increases noise and blast "markedly"? I'm not sure I understand your point with Vais' FAQs. They state the noise and blast are directed away from the shooter. So if a PH, companion, tracker, or whomever were standing beside you or over your shoulder, I can't see how the blast would effect them.

    I've also shot rifles or have been around shooters shooting the Vais, Hart, Hammond, and Weatherby breaks. The point I was making was the Weatherby break although very effective is very loud whether your the shooter or bystander. The others do not have that effect. There are good break designs and bad, and you get what you pay for.

    I agree with you, I have read your comments and you are very knowledgable on the subject. I think there are people that like muzzlebrakes and the improved performance they provide to a shooter. And then there are people that hate noise and will never sit down and look at the physics of a muzzlebrake.
    I like the muzzlebrakes that port the noise forward, Brownings doesn't. I think the increase in noise is from all that pressure being vented through those small holes. Again any loud noise is very bad. I have a muzzlebrake on my 300 Win Mag and it 's going to stay there. It was the cheapest option to fix the gun...the gun didn't fit me right. I will state this for the record, everyone who had shot the gun with the muzzlebrake admires how easy it is to shoot and they hit everything with it.

    Believe it or not, I'm not anti-muzzle brake. I am for facts. If your brake is threaded on get a sound meter and measure with and without the brake from 60 degree off line of fire (probably the closest to the line of fire a guide or tracker might be), 90 degrees off, 120 degrees off and 180 degrees off. Then you'll know. The fact that they make rifles easier to shoot is undeniable. How much additional noise they generate can be measured.

    I too read the Vais site and though they claim to be quieter than others, they dont claim as was claimed above at some point, that there is NO increase in muzzle blast or noise. Facts are facts. If you redirect the escaping gases in another direction, they will be felt and heard in another direction at least within the limits of a particular system and the Vais may indeed be the best, I dont know.
    It also states "most of the noise diverted away from the SHOOTER". That would seem to indicate that those around the shooter will not take advantage of the supposed decrease (over other systems) of increased noise and blast. Also this idea of "porting the noise forward" is silly. The "noise" is the escaping gases, and if you port them forward, what will that do? Increase recoil perhaps? Which would sort of defeat the purpose, no? The Vais system may be the least noisy out there but it will still increase blast and noise for those near the shooter to some degree depending on their proximity. There is no other possible alternative. Even Vais does not claim otherwise.

    And please, I'm not claiming that I know the facts. I would love someone to measure the sound level at the varying angles off of line of sight within a reasonable radius distance (single digit feet) for the various brakes off and on. If there was one that didn't increase the sound level off line of sight by more than 20% I would seriously consider putting one on my 500 Jeffery.

    Anyone who has hunted dangerous game knows that your guide and trackers may not be behind you when you come upon your animal or if they charge. I hit my brown bear as well as he could be hit at 13 yards with a 375 300g swift A-Frame, but he rolled forward and to my right (my guide was even with me three feet to my right) and came up with in 10 feet of my guide and I. I couldn't take a second shot because my guides left ear would've been too close to my muzze (unbraked 375). If he had charged us I would've shot since my guide was clear, but it wouldn't have done anything for his hearing. With a traditional muzzle brake I don't think I would've unless the bear was on me. If you're hunting elk, antelope, mule deer there really isn't anything to be concerned about. If you're hunting dangerous game, I think the equation changes.

    Just my two cents

    I have stated any muzzlebrake will increase noise, no argument. I think they create a cascade of noise because it is spread everywhere instead of one general direction. The Browning brake does reduce recoil more by braking the noise back at the shooter. Some people have theorized someone could get hurt by the gases and perhaps small particles from inside the barrel. Either way it makes no difference to me.
    My personal opinion is muzzlebrakes are for controlled long range shooting and should be avoided for short range work and dangerous game rifles.
    I have been thinking of removing my muzzlebrake and putting on a threaded straight piece since I changed stocks.

    Good rifle, but the factory ammo is way too hot! Downloading the 460 down to 2200 fps will ease the pain on you shoulder and turn the 460 into a great caliber. I was at shooting assessment where a young field ranger arrived with his 460. After 2 shots the (by now deaf ) instructor asked him "how dead do you want to shoot it !" No need for all that speed!

    True am pushing mine on 500gr. At around 2400fps i found the terminal performance a little better than at around2200fps at fps2400fps you still get the weatherby performance......:)

    And .ir shoots like gem i have no recoil reducers ie. Muzzle break or stock reducers ............i still maintain the recoil when compared to 500's and other "large" calibers is negligably different.

    My best always

    I would change my Ceska without looking one of 458 Lott same in ; 460 Weatherby Magnum . I'm not saying Weatherby Mark V for because the price of this rifle is far superior to my Ceska 550 Safari Magnum ... I really like the 460 Weatherby Magnum .

    regards,

    Oscar.

    Yea, it's kind of like castrateing your prized bull.

    Maximum listed velocities:

    460 Weatherby Magnum with 500 grain bullets: 2,550 fps

    300 Winchester Magnum with 220 grain bullets: 2,700 fps

    30/06 Springfield with 220 grain bullets: 2,500 fps

    7mm Remington Magnum with 175 grain bullets: 3,100 fps

    7mm-08 Remington with 175 gr. bullets: 2,600 fps

    A whole lotta speed with them thar 460 Weatherby Magnums.

    My 60 some year old cousin-in-law shot mine several times from the bench and didn't bitch about a sore shoulder or recoil.

    Some testosterone might help.

    this is a very old thread, last post being in 2013.

    having said that, I would like to know what a 460 WBY can do that a 458 Lott cant do just as well. does a 500gr bullet at 2550 fps do more damage then a 500gr bullet of the same size at 2300fps? I would ask if it penetrated better, but the 458 Lott will shoot threw a buffalo length wise and you cant get more penetration then "all the way threw".

    I don't know. Maybe it could put a bullet through an elephant lengthwise?

    Haven't read all the replies, so my apologies if I'm repeating someone.

    The 460 Weatherby is at its best when taken down a notch (my opinion). I have experience (lots) with the 460 and 378 Weatherby. The 460 wears iron sights, the 378 a Leupold 1.5x5 VXIII. The 460 is not nearly as punishing as the 378 (even with full-tilt loads). For one, it's 2 lbs heavier, right out of the shute. For another, it doesn't come back so wicked fast.

    The 378 is best when loaded to its potential, not for dangerous game up close (God no!!!), but for its ability to reach way out there and smack the living daylights out of a heavy of the non-dangerous variety (of course). The 460, though, it's better loaded down (more reliable, that way...again, my opinion). Also, I recommend taking a couple of inches off the barrel (26 inches is just too much, when the game is up close and personal).
