Is a 0 MOA barrel possible?

[kritch]

This would be useless if you made it because of the size and weight but just for conversation...

Say you got a cubic metre of the best steel and drilled a barrel in the centre of it. So the thing weighs a tonne, wont flex, won't move, won't vibrate(?).

If you could shoot it in a vacuum for no wind and all the rest, would this put bullets through the same hole every time at 500m? 1,000m?

At a minimum it would solve shooter flinch

[Chronos]

If you could illuminate the other 30 variables I'd say you could shoot 0 moa

No... You could stick it in the wall of a castle for defences.

Stick it in the far wall looking out the entrance, that could work?

[Granting]

Find yourself having to fortify a castle very often do you, Kritch?

What else...

Perfectly uniform brass.
Identical projectiles... weight, metplats
Powder charges

What else? Can you eliminate differences in primers?

Going for a true 0.0 there would always be something wrecking that last few .01's

If someone gives it a crack though I want photos

Look up railguns.

Not the sci-fi battleship ones... I can't remember exactly but they're used in something like the "experimental" target shooting category. I think it's only a thing in the states really? Not here? Anyway...

They're basically what you're talking about except somewhat practical.

Like a 2" thick barrel on a rail for recoil, and the right is mounted on a huge base which clamps to the bench.

Not 0 MOA, but daaamn accurate.

Or you could just buy a howa

[Bark]

Howa and their famous 0 MOA guarantee

You both spelt Sako wrong...

[BBJ]

You may well be able to make a 0 MOA barrel easily enough.

Making a firearm shoot 0 MOA is a different story though, to many variables to do this IRL I would guess.

Especially if we're talking 1,000 where there is room for error to multiply and show itself.

[RDobber]

I can't spell things that expensive

I'd love to have one of the recent Sako 85 Long Range in 300 WM but it's not to be.

Lucky the Tikkas stack up good too

Yeah I have 6 of them if I fire just a one shot group

[brett1868]

I'm theorising it's technically impossible to produce 0 MOA barrel based on the below -

Will depend on how you measure MOA cause technically on the 50 even if I put 5 rounds through the exact same hole at 100m I'd be getting a 1/2 MOA group. Same goes for every calibre cause every projectile will make a hole of some size because you're measuring the maximum diameter of a circle containing the group. In theory it's technically impossible to produce a 0 MOA barrel though you could theoretically produce one but that's called a steel bar

[Jack V]

You measure groups centre to centre so if there's only one hole it's zero . No one in competition want a zero group because they can't score it and they disqualify the target. If they can only see one hole they don't know if you fire one shot at the target and the others into the dirt . If the target is backed with rubber it will show very closely grouped shots but if they all go exactly through the same hole again no score . It's a bit of a conundrum , everyone strives for the smallest possible group except a zero .
The argument about the barrel is theoretical because there is many other things that affect group accuracy .
However a super rigid rail gun in a windless tunnel could produce a single hole group if all other variable were right. So the right barrel it's self could be capable used in the right situation .

Makes sense, would be annoying though... probably someone out there who's shot a 0 MOA 3 shot group at 100 and thought they missed it twice.

Did it perfect and got frustrated not realising instead

jack doesnt the backer scroll showing every hole? that's the point right to stop competitors putting two shots on target and the rest in the dirt?

The backing rubber will pick up very closely grouped shots that on the paper target look like one hole , but again if they all went exactly through the same hole even the rubber would not show it . I think the main reason is to allow accurate measuring even if the paper target is torn up at the group which sometimes happens and be able to count all shots .
