What part of the stock should they be placed or doesn't it matter. I have a 5" suppressor with an 8" hole length , is it best by the stock bolt by the recoil pad or in the center of the stock. Thanks Tanoose

The brand I used says to install with the line of the toe. In other words, angled down, parallel with the underside of the butt. This puts the mercury at the back end of the tube and on firing, the gun recoils back causing the front of the tube to slam into the mercury. Overcoming the inertia of the motionless mercury is part of the energy absorption, sheer mass is the larger component.

If you install it parallel to the bore, then odds are the mercury will already be at the front of the tube on firing because of the position of the rifle. In that case it is nothing more than very expensive deadweight.

Clear as muddy water, right?

Triggertate;
Best explanation I have heard. Perfectly clear. Also makes sense.

What Triggergate said, it does make a difference. I had two stocks built with the mercury recoil reducers put in them and one parallel to the bore, and one parallel to the bottom slope of the stock, and the latter has less recoil. I think the 'rotation' of the stock is altered somewhat as well, and this probably impacts the felt recoil, but I can't really tell that one stock has more muzzle rise or hits the cheek harder or anything.

These reducers are in a pair of light weight 300 WSM's and made a heck of a difference. My rifle guru tells me that a lead (or other weight) of the same mass would make the same reduction in felt recoil, I don't know, but they ain't that expensive, and I like to think they make more difference than just a chunk of lead up in the stock.......

If weight isn't a big issue to you, I would really recommend trying one.

Good Shooting--Don

Thanks that makes alot of sence i am using a single shot rifle which already has the hole in the stock and it is that way but where should i place it do i put it in the front near the stock bolt or at the end near the recoil pad ?

What tigger said...
I have proven, to myself at least, that the merc tubes are better at felt recoil reduction than lead....

after all, nylon(or plastic) bushings are FAR easier to ride on than steel ones, in a car

jeffe

are they all equal or do you recommend specific brand?

I've got a 375 M70 originally outfitted for a petite woman with mercury tubes in the butt. One is parallel with the comb, the other slanted with the heel. This old rifle also has a 1.5" pad and a 50s vintage muzzle brake. As you would expect this rifle is fairly pleasant to shoot as a result of all this.

That would be a matter of which location balances the rifle best for you. Try both and see how it handles each way.

I have a 16 oz. mercury recoil suppressor in the buttstock of my Ruger # 1 chambered in .416 Rigby. The felt recoil with it is MUCH less than without it, probably equivalent to a 300 Win Mag.
