For the metrically inclined:
40 inches = 1.016 meters
25 yards = 22.85 meters
40 yards = 36.576 meters
1 inches = 0.0254 meters or 2.54 centimeters
1 yard = 0.9144 meters

Sorry I don’t know anything about guns, but is this the barrel getting smaller right at the end? What would happen if you were to fire a solid slug?
Nothing good. It would damage the choke and possibly banana peel the barrel.
Chokes are removable, and it would be advised to remove them for shooting a slug.
Not all chokes are removeable. If you do have a modular choke you’ll damage your gun faster firing without a choke tube in place faster than by firing slugs through a full choke. They make thin wall choke tubes if you want to have an open choke with a modular choke system. From my admittedly 2nd hand knowledge rifled slugs through full choke is safe, but generally inaccurate.
Yup, I have shot slugs from choked barrels on many occasions and it works just fine. Some shotguns shoot rifled slugs a little better with a modified choke than a cylinder choke.
Yes they get a bit smaller at the end to reduce the spread.
Bullets are quite malleable and it’s normal for them to deform a bit during firing. Bullets for non-shotguns typically get forced down a bit in the forcing cone before being deformed to fit the grooves in the rifling.
“Rifled” lead shotgun slugs have these grooves around the outside that allow them to deform down to a smaller diameter. You can shoot them through a choked shotgun barrel just fine.
Brother do you sig fig?
What shot size though? Or doesn’t it really matter, more just a difference in the spread within the spread and a difference in strength of impact?
The particular combination of barrel and shot matters. Even different brands of similar shot, or different shotguns of the same make/model, can have differences.
The chart above is just a general guideline, it’s often recommended to pattern your specific combination to know firsthand how it performs.
I’ve got a pretty decent feel for what I use, but haven’t ever put it on a target, but I guess I was trying to point out that the chart is somewhat arbitrary without listing a common shot size
Would the spread with the cylinder choke also be indicative of the accuracy of a muzzle loading smooth bore musket?
To a degree yes, for that you’d ideally want a uniform barrel. But then again you don’t have rifling, so you’re already not on a great foot.
