Does a floating barrel help?/RIFLED BARRELS FOR $14

[Zen///]

Most sniper rifles have a barrel that touches nothing but the scope and loading mechanism, the barrel doesent touch the rest of the stock.
Most real guns have this for accuracy, but will it work for a homemade air gun? Because my stock from a telescope tripod is great for this type of design.

i doubt this will work for a homemade gun and rifled barrels are uncommon and accuracy is important but that idea would not apply well to a spudgun as they are much larger and the forces involved are much different.

I saw some rifled barrels at one website for $5.

He used a spring loaded ball valve
ABS pipes
a cleanout cap?!?!?
All on a pneumatic.

That guy is no expert and is likely going to get seriously injured using that cannon.

I claim B.S. , come on REMEMBER damn you!!!

[spudgunnerwryyyyy]

Yeah but u need to remember and provide pixs before anybody would order.

Having the barrel free floated, usually in conjunction with being dual pillar bedded won't matter in a spud gun. Remember, "sniper" rifles are shooting bullets at, or approaching supersonic speeds, going hundreds of yards and need to hit within 1-2 MOA (1 MOA = 1 inch diameter at 100 yards). If you want to, you could bed the barrel into a stock. Look up glass bedding.
You should worry about standardizing your ammunition and charges before worrying about barrel harmonics.

[spudgunnerwryyyyy]

I agree with standardizing ammunition. Golf balls and marbles are shown to be the most consistent and accurate especially since golf balls are designed to fly through the air and thus go the farthest.

I think the floating barrel in real sniper rifles are for semi-automatics, so after each shot the gun is still pointing almost exactly where it was before the shot.

In a semi-auto sniper, after each shot the gun will be moved slightly in any direction by the recoil, I think the floating barrel is to prevent this by having the recoil only go through the barrel and not the whole weapon, thus means the gun is still on target for the next shot.

I could be wrong, i'm no weapons expert but this is what I think it's for.
It could be for all rifles or just semi-autos i'm not entirely sure.

But to answer your question, no it would not help in a pneumatic as they are usually so woefully inaccurate in the first place it wouldn't matter.

Also if you did have a floating barrel it could bend slightly under the weight and you will be shooting too low, if you had support you could make sure the barrel is perfectly straight.

It's a good thought, but no. It would be more of a hassle to input onto a launcher than it is worth.

The purpose of a free floating barrel is to keep the barrel from coming into contact with the stock, thus keeping mechanical stresses from acting on the barrel, shifting its alignment. That is how it helps with the accuracy.

I would agree with pyrogeek and put the effort into making better ammo and chamber before worrying about the alignment of the barrel.
