Wide stocks

[Alex Wheeler]

I have been shooting my back up gun lately, 3" with rails. My light gun 4" with rails had me spoiled. Big difference. I will not be building another 3". I had a st-1000, I though it was pretty stable until I cut rails in it too, no comparison, far less movement cycling the bolt. I agree, wider and rails is the way to go. Try it, I think you'll be presently surprised.

I caught that Viper jab, Tom.

If you look the 6 and 10 match aggs. both score and group have been getting smaller each year and the final positions are a lot tighter. It is also getting a lot harder to win a relay. These rule changes and gun changes have a lot to do with that. When you sit down and look at whose in the relay there is a lot more competition. Matt

Please Explain.

My grandmother is a nuclear astrophysics and told me she is intrinsically cretin that the wider stock with more hora zonal surface area could be affected by solar particles collecting on the surface and become negatively charged thus causing a positive ion collision which in-turn would generate a magnetic field and cause the bullets to be drawn toward due north and off the target. That explains why most records are held by 3 in. stocks. I think therefor it would be better all around if everyone sticks with a 3 in. wide stock. We all know the earth is flat after all......

Please let us know what you find. As far as the piano reference, I dont believe its because a wide board vibrates more, just that it has more surface area to transfer the vibration to the air.

JRS,
Then a 2" stock would be better?

I was thinking about milling rails into my Shehane Tracker II that my 6 Dasher sits in. Any suggestions on how wide/deep the rails should be?

JRS,
Tell me why it matters. I don't believe a bullet will traverse the center of a solid rod.

I don't have any degree but i will tell you this, you all are talking about how wide the fore end is you better look how high the barreled action is in the stock and how top heavy the scope is. My PR&T stock is so low that and stable and tracks so good that you may have to adj half the 10 shot string at the most. It will shoot in the low 4" range, it may do better this year it's glued and screw…… This is only holds true if you race a condition, if you are a picker it doesn't matter. I don't think a heavy shoots any better than a light gun but maybe easier …… jim

JRS don't be putting down my Grandmother.

 

[JRS]

I re-read my comment, and most certainly did NOT put down your Grandmother. As a matter of fact, I didn't mention her at all!

Back to the discussion about the stocks. If I use a 6" wide stock, inlet the barrel channel, then hollow out the bottom so that only the edges of the stock ride the bag, I would have nothing more than a 6" wide tuning fork. Surely we can agree that a 3" wide solid bottom stock isn't going to vibrate the way that that tuning fork will!

We're talking about vibration, and vibration only Butch.

How big is your scope? How long is your barrel? How heavy is your barrel?

They must be a trade off, You know, where performance out ways vibrations

I think a wider stock using rails will have less bag miss-q's and less torque when running the bolt..JMO

JRS,
I really am not trying to be an AZZ, but the way you are stating it, the most narrow fore end would be better. I believe wood dampens vibration more than the synthetics and that is what I use. I know what you are stating, but in practice the wider fore ends are an advantage. Think of it this way. The vibrations are coming from the barrel, not the stock. If you used the proper calculation, wouldn't the wider fore end absorb more of the vibrations and better deaden them?

 

[Alex Wheeler]

JRS,
I am not arguing the science. But I don't think it applies to a rifle. If you hang a barrel on those different width boards, the widest will vibrate less because it is stiffer. I don't think you can argue a wider stock is stiffer, and should the vibrate less.

 

[dkhunt14]

They are only hollowing out thee area that rides the bag and only about 3 inches in the middle by 1/8 inch deep. Just so it doesn't contact the bag in the middle and rock. No tuning fork at all. Matt

 

[Raythemanroe]

When your talking vibrations I would think shape, material, glues would relate as much.. I think sand is a good vibration dampener and rail like forends may have less contact therefore receiving less effect from the sand bag...

Right on Jim, my Robertson stock has the barrel way above the bag and it is a torqueing sob.

One thing I noticed about vibration is if you cover the benchtop with plywood the vibration disappears. Years ago I got one of Ricks aluminum light gun stocks. I went over to my buddies place to test at 400 yards. I put in a concrete bench on a pad. When I would shoot and watch for impact the crosshairs would vibrate so bad you couldn't see the hit. It sat there for about 15 seconds vibrating. I went home and got a big piece of 1 inch plywood and came back and laid it on the bench. When I shot the vibration almost was completely gone. Matt
