Ok so Ive been shooting for a few years now over 10 and like to think I understand the workings of a shotgun well enough to consider what chokes to use etc.
I have been told that a longer shotgun barrel will increase the speed of the shot by a rate of 5fps per inch and with added choke this will increase again. Basically I have been told information that has been read in an article online, see link below.

Now I'm not saying that this is all rubbish, far from it, but for the average shooter is 5fps worth anything or is it just something of nothing considering a bog standard English Sporter cartridge for clays (28grm 7.5 fibre wad) is going at 1350fps anyway? (speed quoted from English Sporter web page).
My understanding is choke mainly effects the pattern in terms of spread/density, at given range loosely speaking and barrel length will mainly have an effect of the guns handling characteristics.
If Im wrong please feel free to correct me. Also is there reason to consider shot speed if it only increases by 5fps per inch?
