I have a wood stocked 458 Win mag with a Pachmayr recoil pad that I'd like to add a mercury reducer to, both for the guns balance and to tame the recoil. How would I go about doing so? | ||

I have always wondered whether those gadgets actually do reduce recoil. | |||

If the pad is just screwed on, take it off. If it is epoxied on, use a bandsaw and carefully cut right at the stock/pad junction. Then you will have to use a 12" disk sander to square the buttstock and the pad. Very carefully drill a pilot hole about 1/3 the diameter of the mercury tube parallel with the bore and in the heaviest part of the stock. You'll have to carefully plan this out before you drill. After the pilot hole is in you'll have to bore it out with a wood bit to just the diameter of or slightly over the tube diameter. The directions will tell you if it needs to be bonded in but, I didn't on the one I did. Reinstall the pad and you might consider bonding it on with epoxy. If you do that, make sure the surface glaze is sanded off the mating surface of the pad and remove the finish from the mating surface of the stock. Wrap masking tape around the outside of the buttstock where the pad fits so that you won't get the epoxy on the surface of the stock. Use vineger on a rag to wipe any overflow of epoxy off the stock and your fingers. This will only work while the epoxy is wet. "I ask, sir, what is the Militia? It is the whole people.

My Merkel 470 SxS came with a solid steel weight in the buttstock. It came with a hard rubber buttplate which I replaced with a Pachmayr Decelerator . After approximately 10 rounds the weight sheared the bolt holding it and tried to punch thru the Decellerator. I merely removed the counterweight and continued to use it without the weight. The reason I write is because the Decellarator is actually hollow and I believe would allow the mercury reducer to move against it. I personally would put a retainer across the hole. I think the hard rubber buttplate on the Merkel was performing this function. I have used the mercury reducers in several doubles and find them to be very effective.

The mercury "reducers" actually work by spreading the recoil impulse over a longer period of time. The "felt" recoil is less because the recoil impulse is converted from a sharp spike to more of a sine wave configuration. Instead of a sharp rap you get a really firm shove. Geronimo | |||

they work better than just weight, will throw the weight backwards, unless your rifle is very nose heavy. easy enough to remove Hey Guys, on the glued on bad, put them in a freezer and TAP them off, after 24 hours... generally will come right off.. if not, THEN you can saw it off opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Do a search in the Gunsmithing Forum; it has been discussed there numerous times over the years. I installed one (the CH 5â€, 16 oz model) in my Ruger 416 Rigby and my son and I just took her out for her maiden run this past week. We found the recoil to be tolerable. Shooting his 340 Weatherby Accumark was a bit worse, sharper slap than the Rigby which was more of a big hard push. While we have not fired it with and without the reducer to truly compare the effect, just the weight has to help alone but I believe they do reduce the snap as has been noted by others. We drilled the hole by mounting the stock in my drill press table at the correct angle and clamping it securely but padded. We used an adjustable spade bit to drill the hole just very slightly oversize (just over 1†I think) and went very slowly pulling the wood chips out continuously with the shop vacuum. I was lucky enough to get a Ruger with a beautiful piece of Circassian and while it was dicey drilling the hole, all went well in the end. If you are not comfortable doing it yourself C&H will install it for $50 I believe. For reference here is a thread that I started on the proper angle for installation but as I said there have been other threads in that forum. Proper angle for installation of a mercury recoil supressor? Good luck "Diligentia - Vis - Celeritas" NRA Benefactor Member Member DRSS | |||

I have only one on a rifle so far, but based on how much better it feels to shoot, I am thinking of adding them to a few other rifles ( and one particular shotgun) Si Vis Pacem, Para Bellum | |||

Yah, what he said! I'll also add that the additional weight in the buttstock of the Rigby seemed to balance the rifle better, as it's pretty front-heavy from the factory. I was surprised at how easily we were able to get back on target after a shot. _____________________________________________________ No safe queens! | |||
