Steel shot and half choke

[Old farrier]

 

Don't worry - I'm not going to get started on this one, but I have to ask:

 

If they stretch, what's the point?

 

I mean - 0.035"-0.060" constriction chokes for steel are what they are and people will use them or they won't - but if they're only (say) 0.020" constriction when the shot is going through them, what's the point? Why not just use a plain old half choke?

Carry on with your half choke 😊😊

I'd much rather have a full with a bit of stretch that gives me a tight 3/4

 

All the theories in the world will not equate to practical tests lots of shots through different guns and chokes with different cartridges

 

Note all metal stretches or expands contracts especially guns

That's how it works in the proof house

 

To the OP

Sorry about this seems to have gone off from your question a tad

Well yes, that was the point of talking about the Young's modulus of various materials above - it's a measurement of how likely they are to deform and allows us to quantify this stretch / expansion. I had thought that by discussing the modulus in the context of barrels, pellets and chokes that I'd implied the elasticity of metals satisfactorily.

 

Also relevant to this discussion are the factors relating to metal fatigue and the various strain regions of the substances involved expressed as a function of strain vs deformation, of which the Young's Modulus for the material describes the linear part of the function before the substance's elasticity is exceeded.

 

I repeat the apology to the OP.

The stretching will be minimal and continual and will effectively wear out the choke eventually.

 

Throw it away and fit another one!

 

Hence the suggestion to use extended chokes which in effect become sacrificial and save the gun.

The only problem I can see, is with all the pushing 'n' shoving 'n' stretching going on, when it comes to replacing the choke, what state are the barrel threads going to be with regards to accepting a new choke with the original thread profile.

Just saw a bit of the end and re thread it 😂😂😂😂

That we have yet to find out, let's hope the choke takes all the pressure and the choke pocket is fine.

Manufacturers say to replace the choke tube when it becomes tight in the threads before damage to the barrel and threads can occur.

Yep.

It may well be prudent to call "tight" the point at which the run down torque exceeds finger tight.

Never heard that one.

Appreciate the science

 

What do you recommend we should shoot the steel through

Or should we use something totally different

 

All the best

Of

**** guns we don't care about!

I have a Baikal O/U for just that purpose!

_{It amuses me how some folk view steel cartridges, as if they are somehow dangerous, or guaranteed to ruin all shotguns.}

[figgy]

Motty eventually steel shot being as hard as it is its going to damage something, i have had pin holing in the wads on steel carts and never seen any marks to my barrel.

 

Pushing steel through chokes when the shot wont give something has to give, any changes may not be seen for a number of years.

 

Your correct steel carts are not dangerous used in the correct guns.
