can anyone vouch for the effectiveness of these, and how much they unbalance and/or waeken the stock seeing as a hole must be drilled up it in order to accomodate one.

Some people say they are no more effective than a chunk of lead of the same weight.

I disagree. The movement of the mercury within a tube distributes the recoil OVER TIME so that it becomes more of a push instead of a sharp jab. I love mercury reduers.

I hate to disagree with 500 grs. but mercury reducers have little or no effect on recoil in the big kickers (460 wby. up)IMO. An A-Square 577 T.Rex has 3 mercury reducers and will still kick you into next week if you don't have a muzzle brake. I also had them on my t.rex. and I did not find them to be effective.

I am getting two in my .585 even if it is just the placebo effect everything helps.

I've heard you'll be able to get to 2575-2600 fps with a 750 gr.bullet in the .585 Nyati with a 26 inch barrel,,and how are you going to manage to get to a level like that ?!
Yes i must confess that it sounds optimistic, but maybe memory fails me, maybe i heard wrong, but it still sounds OPTIMISTIC.

per577, Take a look at the .585 Nyatti section in this website under reloading. They acheived a tad over 2500 fps with a 750 gr bullet from a 23.5" lothar walther barrel.

I would suggest NOT to load the 585 Nyati to more than 2400 f/sec when used in hot climate like in Africa. The 577 Tyrannosaur should not exceed 2550 f/s ( but 2400 will be enough..). Just to avoid pressureproblems. A sticky case migth be ok on the range, but it can make a little problem when hunting buff.
Regarding mercury recoil reducers I have some experience with them in my 577 and in one of me previous rifles in 416 WBY caliber. I think they work great. Definately reducing recoil- but whether it is the mercury flowing in the tube or just the extra added weight I don�t know...

I would suggest not loading the 585 nyati to high pressure with Bertram brass or you will get stick extraction.

Mitch,

Perhaps your loads overpowered the mercury reducers, rendering them ineffective?

I have been quite pleased with the mild recoil in my 458 win, 458 lott, 470 capstick and 585 nyati. The lott has 3 of them and it is like shooting a .270. Or maybe I was dreaming it would only kick like a 270...

Here's the physics
1:Energy travels faster through densier material
2: felt recoil is lessened with additional weight

So, facts are that the tube does add weight, it also spreads the "moment of recoil" (my term, as moment of impact can't be changed, as impact is usually defined as usually instananeous)

If it overpowers your reducer, have a longer tube made, or larger diameter. Much like recoil pads, they can be overwhelmed, or, more specifically, the felt change vs recoil can be felt to be huge.

Let's face it, the number that people throw out there is a 460 weatherby... and, in reality, only the 460, it's based wildcats, the 577 ne, 577t-rex, 585, and other huge things whallop you with more than 100ft/lbs of recoil. If you are used to 50-60 #, and move up to 150# effective (guessing 200#-25% with recoil), then your total impression might be skewed.

This is much like the 50bmg shooters, that say "you CAN shoot the 50 without a muzzlebrake, but you will only do it ONCE"

What do you guys think, who shoot the 577+?

How do you take your Hg "recoil reduced" guns on an airplane? Isn't that prohibited? (Or do you just "don't ask/don't tell"?

I'm sorry guys but I've played with the mercury recoil reducers and my fundamental observation is that other than adding more weight ( which is a good thing in and of itself), they are no better than filling the butt with an equal amount of expoxied lead shot. You have to be very carefull about not completely screwing up the rifles balance with them. I've had to add expoxied shot to the forearm to compensate for the additional butt weigh. In fact they are far far inferior to adding a effective muzzel break. I don't bother with them any more.-Rob

ok, well just how much does one mercury decelerator wiegh?

They make mercury reducers in 8 oz and 4 oz versions. One 8 oz in the butt and another 4 oz in the forearm works out just splendid.

4,6,8, most common 11, and custom orders... the 4 is semi custom.
I like em, but then again, i like heavy weight guns

I have had 2 different stocks on my t.rex. one with mercury reducers and one without. The be honest I could not tell the difference. Most of the time my loads do not exceed 2400 fps with a 750 gr. bullet. so I don't think I am over powering the mercury reducers.

I Put one of the 8oz ones in my ruger #1 and it helped recoil and ballance both. As to stock weakness as long as you stay away from the wrist it makes no differnce.

U've used Edwards Recoil Reducers in various shotguns over the years and I've found they do have a positive effect...especially if the gun doesn't quite fit you. Edwards are made to be used in pairs and they are set up at an angle to each other with the "result" the opposite actions furher reduce recoil.

500,
high pressure loads in the Nyatti & T-rex may also cause "brain extraction"

PC,

These days, before I shoot my 585 I take a Tylenol. Then I take another when I get home. Plus a nap.
