Stock Vibrations

this might make for a good topic, and its a situations i am dealing with. I have a stock that i am experiencing a lot of vibrations with. During recoil i can see the vibrations of the rifle through the NF scope i put on it yesterday. It really kinda looks like a POOOEEEEEIIIINNNNGGGGG after i brake the shot. The gun is heavy enough that i can see this with a good follow through during recoil through the NF. I know this isnt ideal and it has bothered me ever since i saw it. This particular set up is one of my very favorite that i own but it isnt my go to set up, as the consistency just isnt there. I have shot some fantastic groups with this rig, but not consistently. I always thought that the action needed some work but now i think its the stock. When i got home i held the rifle in my left hand and smacked on the side of the rifle with my right hand and i can feel the vibrations for at least 2 seconds before it settles down. Its really a ssspprrrinnngggyyyy feel. Kinda like hitting a plate of steel with a hammer, you know the vibrations you feel after doing so!! Is there anything i can fill the inside of the butt stock with to help dampen the vibrations? Any other ideas?? thanks Lee

PS This isnt a bash the product type post so i will not say what stock make this stock is so please dont ask. I love this stock as it is one of my very favorite designs made and very popular among the bench rest crowd. I may just have this thing way over weight for its intended purposes. It was set up as a 13.5 pound class rifle but i have since added a small amount of weight and a 26" HV barrel. rifle weighs just under 15 pounds. Lee

Something loose... barrel, action screws? Does it need to be bedded? - nhk
 
Hi skeetlee



Interesting !

More details would really help.

And possibly a few photo's too.

Glue - in or screw in ?

Bedding material?

Caliber ?

Skeet, one of the more popular stocks in use, made of Carbon Fiber, has that very characteristic. The fact that multitudes of shooters win with it tends to make me believe it is a non issue.

What you are seeing through your scope is probaly not vibration. Ever look through a Rail Gun scope when you fire the Rifle? It looks like all hell is breaking loose out front. And it is.

But it doesn't seem to affect anything.
 
Lee, my best shooting gun does that. Everything is fine until I get in a hurry and shoot too soon after sliding it into the forward stop. I am trying to remember to keep a finger touching the barrel as I push it forward to damp the vibrations.

about a half dozen of those vibration dampeners used on compound bows , stuck to the side of the stock ought to help. probably look silly too!
 
Thanks fellas. Like i said i have shot some fantastic groups with this rig but it inst as consistency as some of my others. A while back there was a post about BAt bolt mods and i think this action is a good candidate for that work. I don't want to give up on this rig as i really really like it. the stock fits me very well and that means a lot to this retired shot-gunner. I think ill send the bolt to Dave Bruno and see if that helps with the consistency. thanks again! Lee

If i were to add some lead shot to the back end of my stock what kind of material could i use to mix with the shot that would harden. Kinda like a lead epoxy mix. I know Tom M does this sort of thing when adding weight to stocks. I would like to find something that sets up semi hard and that would have some dampening property to it. Any ideas? Lee

Ya butch i have a couple terry Leonard stocks and they are tops for sure. I haven't ever had any issues with my glass stocks until know and it sounds like i still dont really. But yes i do like wood stocks no question! Lee
 
Skeet, what you want is a Devcon Product called Flexane. It is a two part mix, is pourable, and hardens into a hard rubber like substance.

The back of my HV 30BR is filled with Flexane.
 
Kevin its made by McMillan. I have talked with a few fellas that have or have had this stock and i think its is probably ok. When i get the time i will do some serious testing and make a determination. I put a longer heavier barrel on this stock this past weekend as it was a new barrel and i just wanted to brake it n a little and i was surprised to see the vibrations caused by recoil through the scope. i guess i have a good follow through as i have been working pretty hard on that area of my technique. It just looked as if the rifle would never stop vibrating. I haven't ever noticed that before while shooting a ppc or BR on this stock. You know, i just dont know. I love this stock, i really do and i dont want to give up on it, so i wont. I love finding out how or what makes a rifle shoot as well as what hurts accuracy. It is all very interesting to me, and i like sharing my experiences with you folks. I live a pretty low key life and my needs are simple. I need my family and i need to play with rifles, LOL!!! I will report as i find anything. Lee
 
Lee,

I think I mentioned this to you but maybe not. Tom uses a very unique way of bedding McMillian Stocks. It makes the bedding area more structurally sound. If a small void occurs in one of two places during the final glue-in, it is possible this ringing will occur. Having not seen or heard you particular rifle do this, I can not tell you whether its normal or not but it might need the action pulled and reglued. I've never had a rifle that Tom did ring like that.

One way to possibly narrow it down, put a finger on the side of the action (very lightly) when you fire it and see if it seems to generate between the action and stock or if it's just the stock. If it's the bedding, you will feel a buzz through your finger tip instead of a thud (best way I can describe it). Take one of the lenoards and fire it the same way and see if you feel the difference.
