Right, I could never get my head around the principle of using filler in a revolver to space the projectile closer to the barrel to gain more accuracy.

How does this work? The projectile still has to engage with the rifling and then travel the length of the barrel so how can the depth of seating in the chamber affect it?

I have always believed that the muzzle had the most important part to play as this was the last part to be in contact with the bullet.

Answers on a postcard please.
