Rifling the barrel imparts spin to the projectile, which helps to stabilize it and keep it "right end first". Projectiles fired from a smooth-bore weapon are much more subject to tumbling, which doesn't make much difference if the projectile is spherical but makes a very big difference to drag and therefore to range and accuracy if the projectile is NOT spherical.
No, a rifle has rifling in its barrel (spiral grooves to make the bullet spin, thus stabilizing it and improving accuracy). A musket barrel is smooth.
You did not specify the make of your Model 300 (there are several), but in general, a 12 g shotgun CAN fire slugs from any standard barrel. You will get better accuracy from a slug barrel, but you could use any barrel OTHER than an "Extra Full", or a shotgun with a variable choke.
No. The lead of the shot is MUCH softer than the steel of the barrel. However, if you have a RIFLED slug barrel, expect poor accuracy with any shot load- the rifling will make the plastic shot cup spin, and as it leaves the barrel, centrifugal force will make the shot pattern open into a "doughnut" shape.
As a wall hanger, sure. People occasionally pay surprising amounts of money for them. But even if it were possible to unblock the barrel (NOT recommended!) the accuracy of the barrel would likely be destroyed. Best and by far SAFEST idea is to make it a wall hanger.
No. It will not effect speedometer accuracy.
The spiral grooves in a guns barrel are known as rifling. Its what puts a spin on the bullet as it leaves the barrel for accuracy. The grooves are called..... well, grooves. The ungrooved part between grooves is called a land. So looking through the barrel of a rifled firearm, you will see the "lands and grooves" that make up the rifling.

Bullets rotate due to the grooves that run down the inside of the barrel walls in a "helical" shape - this is known as "rifling". The grooves make contact with the bullet as it it fired down the barrel and cause it to spin. This improves its aerodynamic stability and accuracy.
Lands and grooves are the portions inside the barrel that make up the rifling, which is a spiraling series of raised lines (lands) which put a spin on the projectile as it travels down the barrel. This stabilizes the projectile and allows longer range and better accuracy.
You improve your model through a better understanding of the underlying processes. Although more trials will improve the accuracy of experimental probability they will make no difference to the theoretical probability.
