Answer
In long rifle, the musket is long and hence, the push force applied by explosion of gun powder works for a longer time and because the musket is long it is easier to provide proper direction to the bullet. The accuracy is higher as the bullet will travel a long distance with large velocity only in the direction that the gun is pointed in.
