Composite stocks

I know there are several guys here with experience with various composite stocks. I just picked up a Greyboe to replace the composite stock on my VSSF Remington 700, I'm not sure who makes the factory stock HS or B&C? The reason for the replacement stock was the rifle barrel oscillated up and down pretty badly in the factory stock. I mounted the barreled action into the Greyboe and fit was perfect, so I went to the range to see how it would do. To my surprise the barrel ossilates up and down just as badly as the factory stock. The rifle is very accurate and maintains the same point of impact with either stock mounted. So I am wondering if this is just a trait of composite stocks?
I took the factory stock and bedded it to my 16" heavy barreled 22-250 and it seemed to help, but did not cure the occilations completely. I have not bedded the Greyboe yet, because if it is always going to oscillate during firing, I will return it and go back to wood stocks.
All shooting has been done off of either Harris or Sinclair bipods. So, what are your thoughts on composite stocks? Thanks, DH
 
Unless I've unknowingly had a stroke and scrambled something my post seems pretty strait forward. Is the barrel oscillating up and down inherent to composite stocks?
 
I have many rifles, and none of them behave this way. They are all mounted in stiff wood stocks though. The barrel is moving up and down roughly an inch at the crown, which seems excessive.
 
I was watching the barrel while my buddy and the range master fired the rifle. You can also feel the vibrations going through the rifle while firing a round.

The VSSF Stock is made by H-S Precision, and it is the same composite stock used in US M-24 military sniper rifles. They are damm good.

What makes you think that the barrel "oscillates up and down"?? Especially if you also say the rifle is accurate. Barrels that oscillate up and down, are NOT accurate.
 
I'm wondering if this will become the next new "once every two weeks" question here on PM?

I'm with the "Huh?" remark on this one.

So what's the problem?!?!?!?
 
I didn't think this was a dumb question, but I stand corrected. I am familiar with barrel harmonics, and this issue seems different. I'll keep working on it, thanks anyway.

Either this or you may need to clean the fluggle horn.

In all seriousness, if you have a rifle that whips the barrel a visable inch of deflection at the muzzle, AND, still shoots well, my friend you have one very magic rifle.

I'm still trying to figure out if this is a real question or if the OP is just messing with us to see what kind of crazy solutions will be suggested. lol
 
I would think if you could actually see the barrel oscillating, its about to fall off the receiver.
Ease up on the herbs Dirty Hippie!!

I too, without knowing anything about the OP other than his user name, was going to at least suggest that if it were applicable that he might consider putting his bong on the shelf 10-12 hours before heading out to the shooting range to see if that alone would reduce the oscillations.

And from a purely practical point of view, I hope that no one on the internet told the OP that you don't need the front action screw with a composite stock.

On a more serious note, I had inner ocular surgery on both of my eyes several months ago and the process reversed my vision from 20/40 with glasses to 20/15 unaided in both eyes. If the OP can see a barrel oscillating, I'd still be interested in meeting his eye specialist, even where I am now with my "youthful" vision.

There is no way your eyes and brain can resolute barrel oscillation in real time. That action is over in a fraction of a second. You would need some very good cameras and other equipment to catch that.

Ya think?

When most people discuss barrel whip or oscillation, many people think in terms of the barrel oscillating up and down as the rifle is fired. Some of this does happen due to the pressure loading on the steel throughout the length of the barrel as the slightly larger bullet travels down the barrel under considerable pressure. When this pressure loading takes place, and if the barrel is bedded in the stock, the barrel will in most cases oscillate up and down somewhat in proportion to the stock pressure on the barrel. A free floated barrel obviously oscillates less up and down with all conditions other than stock pressure being constant. No stock pressure generally translates into less up and down barrel whip.

But due to the fact that the barrel is rifled in a twisting pattern down the length of the barrel, a sporting rifle barrel, or any rifled barrel for that matter, regardless of size, also oscillates in a somewhat circular pattern which also affects where the muzzle is pointing at the exact moment in time when a projectile leaves the bore. The best way to visually describe this circular oscillation is to hold your right arm and hand out straight in front of you with your index finger pointing straight ahead. In this position, now move your index finger in a small circular motion in the direction of the bore twist on a barrel. This is what a barrel does in varying amounts that differ with barrel diameters, caliber diameters, and (gasp) barrel twist, just to name a few variables that affect the overall circular oscillation.

And seeing it all happening does indeed require very sophisticated and high speed pressure recording devices as well as extremely high speed photographic equipment to be able for the human eye to see it in slow motion. At normal real time speeds, you hear a bang and you see absolutely nothing in the way of barrel oscillation.
