The British Army traditionally put a lot of training into musketry, and even in modern times spend a lot more time worrying about the ability of an individual infantryman to shoot accurately at long range than many other armies.The English were also very good a musketry battles, because they had a solid wall of lead going towards the enemy with her volley. It was a great wave effect when they fired, right down the line one at a time. I forget what this is called but they speak of it alot in the Bernard Cornwell Sharpe's Series.
In Napoloenic times it was standard practice to hold part of a regiment's volley back, so that notwithstanding the slow rate of fire of the musket a more or less continuous fire was maintained. I am not sure why that was so much more effective than one large volley, possibly because with one large volley the men at the head of the enemy column are shot more than once, wasting fire, possibly because if the first part volley was held back until the enemy was close, then if they continued advancing the second part volley would still be available before they closed fully, and at really very short range.
But I don't think anyone these days really knows what musketry battkles were like or how they really worked.
