Technically it could be considered a "break" because that is what it does to your eardrums. I always use ear protection at the range and don't in the field. Just a few shots with my Weatherby 7mm and my left ear has a little damage. I'll never buy another rifle with a muzzle brake unless I can cap it or replace the barrel.
I have only shot it at the range with the brake on it and ear protection. The factory loads are humming along at about 2650 fps for the 500 gr FMJ. One load I got it up to 2700 fps. If I hunt with it, I'll load them to about 2400 to 2450 fps and cap the end. It wont be much worse than my Lott at 2320 fps.
In the two 460s I had 115 grains did right on 2500 with 500 Hornadies. At just over 2600 I started to get ejector marks. But my brass might have been softer.
How do you find the recoil with the Accubrake. I have only used 460s with the Pendleton Dekicker.

The 123 gr load started to get a little sticky on the extraction. No ejector marks. This was once fired Weatherby brass. The Accubrake does it's job. The 460 kicks noticably less than my 458 Lott. The Lott is now somewhat tamer since I added a mercury recoil reducer in the stock. It weighs just under 11 lbs with scope and sling. The balance is nearly perfect. If you can call an 11 lb gun balanced.
I will probably add two recoil reducers to the 460 because of the weight of the barrel and the extra velocity. Should be about right. By the way. The 460 was just a barrel, action, and trigger that I ordered from Weatherby. I put it in a McMillan stock. The gun looks like Darth Vader's death ray.
My Brake is not to bad as all the holes are drilled 20 degrees forward, so I think that helps. I am aware that it is my only brake, but it seems better than the porting on my 16 1/4" barrelled .44 rem mag marlin.

Longbob and Mike, Somebody on HuntAmerica was claiming they were getting 2720 FPS across the screens with their 460.
Weatherby isn't selling barreled actions cheap at all anymore.When I was in the market for a 378 a few months ago,I checked it out.$1550 for a 378 or 416 barreled action,a bit more for the 460.I got my brand new unfired Mark V Deluxe 378 with Accubrake for $400 less than what Weatherby would have charged me for just a barreled action!!
The McMillian stock will take the 460 with only one recoil lug.They're the only stock that can claim that too.
Longbob,folks I have talked to say that their 460s,loaded to the max with 500s,kick about like their 9 pound 375 H&Hs when they use the Accubrake.Do you agree or disagree with that??
The Weatherby site says that the full house 460 with the Accubrake has the same recoil energy as a 375 H&H. I have a 9 lb 375 H&H in Winchester Model 70 SS with a McMillan stock. It may be purely psychological, but the 460 seems to kick considerably more. It may have some to do with the concussion of the Accubrake that makes it seem so violent.
If the Accubrake was 100% efficient and you ignore any retarding effect from the gas hitting the metal that forms the holes, the recoil with 120 grains of powder and 2600 in an 11.5 pond gun would be 53 ft/lbs.
Add some because the brake can't be 100% effcient and you would be at maybe 60 ft/lbs. Be less than an unbraked Lott weighing 10 pounds or so but a fair bit more than a 375. How does that compare to your shooting the gun?

I think breaks must work very well, I also now think that by using a break and reducing recoil you may also be placing your stock mounts & scope under less pressure. I am now considering getting one for my .416 rigby. I am also of the opinion that mercury recoil reducers despite what others say help to a certain degree. With a combination of a good stock (I feel weatherby style is great for hard kickers)and some recoil reducing devices such as a break and mercury reducers and sensible weight for calibre big bores can be comfortable to shoot.

A "brake" may actually be harder on a scope than none at all. It yanks the scope back foward to a degree. One way that you can ruin a high powered rifle scope is to place it on a 22 rimfire. Leupold makes special rimfire scopes.

How so? Iknow that a spring/air rifle can destroy a scope due to its dual recoil action, but I don't understand how a "non recoiling" rimfire could.
Longbob and Mike, Ya'll are probibly correct about the recoil with the Accubrake.The 378 with Accubrake kicks about like a 300 Winchester Magnum from an 8 1/2 pound gun,or at least that's how Mitch and a few other guys have described it.It would make sense that the 460,which kicks roughly 60% more than the 378 when both are unbraked (80 versus 120),would kick a whole lot harder than a 375 H&H when braked if the 378 kicks like a 300.Figure 30 foot-pounds for the braked 378 would put a braked 460 at around 50 pounds or so.An unbraked 458 Winny or 416 Remington churns up around 65 pounds,so with the brake it shouldn't be all that bad.
I'll definetly get a 460 with the Accubrake to complement my 378 one day.
Hey longbob ! So could you tell me about the Darth vader gun, with the mcmillan stock,,prize,,and a little comment on your max loads. How was pressure firing 500 gr.FMJ out to 2685 fps, with 113 gr. of imr-4320 ?
Well, I hate muzzle brakes too. As soon as the load gets ready to zero in, the brake gets gone and stays gone. I would rather have a 25 pound bag of shot than a muzzle brake, for load development preliminaries, however.
My favorite 460 WBY load is that 115 grains of IMR-4350 mentioned above by Mike375. My BBK-02 shoots about 1/2 MOA for three shots with this load, giving the Hornady 500 grainers about 2500 fps ... long ago, in a galaxy far away ... I used to get it out once a year on my birthday, just for kicks. Still do occasionaly. It has a laminated stock with a lightning bolt checkering pattern on each side of the forearm ... did it myself. Mjollnir is the name for this Thor's hammer.

I have become much more inclined to the muzzle brake since I arrived at the stage of wearing ear protection irrespective of what I shoot or where I shoot.
They can certainly turn a 416 Wby into a 375 for field shooting.
Strange as it may appear, at our range, a big bore, for noise, is better to shoot with a brake than without. Small quick bore is different.
This happens because there is a large board that runs down in front of all the benchs to stop shooters elevating the rifle. The board is about a foot or so out from the muzzle. What happens is that the brake stops all the gas hitting the board and coming back. Behind the benches there isa loading room. When a bloke is on the becnh next to you he of course really notices a 460 etc go off with the brake on. But when he goes into the shed to load ammo he will always come back out and tell you how that in the shed the big banger seems quiter than the other rifles.
Actually, I suspect with a muzzle brake my hearing will be better off as the brake completely removes the option of not wearing hearing protection while shooting. And the recoil of the 416 Wby or a 460 at full power removes the option of removing the muzzle brake

It is my understanding that a 22 rimfire's (semi-auto) harmonics are very similar to an air rifle's. The construction of the internals of the rimfires scopes are altered for this reason. This is why some of the scope manufacturers recommend their rimfire scopes for air rifles. If you have information to the contrary, feel free to share it.
My "Darth Vader" gun was about $1,400 USD for the barrel, action, floor plate, and trigger. The McMillan stock was another $400. I have a Leupold M8 2.5x Compact with Talley QD's. When I get back from my trip, I'll post a picture. My camera is packed.
I didn't notice any pressure signs with the 113 gr of 4320 other than on my body. The concussion with the brake rattles your nads. I'll probably load it down to about 2400 or 2450, remove the brake, and install a couple of mercury recoil reducers in the stock. This should be about right.
Thank you Longbob! That's amazing,,113 gr. of imr-4320,and 2660+ fps with 500gr.FMJ's. In weatherby load catalog 2001,they list 108 (imr-4320)as max, and vel. was 2550 fps ! That was Hornadys data .I think it was both FMJ AND SP.Well i ask anyway,,but do you think 2700+ is possible in your rifle ?
There are three things you should consider about my loads and velocities. I may have a "fast" barrel, my Chrony may read a little fast, and you may not be as stupid as me.
Ok, Longbob,,i shall keep that in my mind ! But heck,,norma(weatherby) brass are very strong i believe.But i'd rea would like to have a special gun made for me in .460 Weatherby that will do well over 2600 fps. I hope you could answer me this ,but don't velocity increase if the twist is fast like 12", or 10 twist, and lenght of the barrel of course,,and people are talking of them grooves. The less groves the more velocity or what.( i read about it in the .600 OK topic, robgunbuilder sure has some answers to this matter(grooves in the barrel)). I also think one could get a barrel made for velocity,,maybe Pac-nor make such high vel. barrels ,or what !?I sure want a .460 Weatherby that gives a certain amount of adrenalin rush,pulling the trigger of the got damn thing !

Hello to you Brian ! I have been searching all over HuntAmerica (a damn good secundary source next to accu...of course)I did not find anything on the .460 Weatherby with loads exceeding 2720 fps !!Could you help me out and tell me what load, bullet,and where you found it ?
Per577, Sorry for the late response.Go to search and type in 460 for all forums,in the last two months.You'll come up with it.I think it was a guy named Bill T but don't quote me on that.
