Quite... the difference between good striking and bad striking is quite noticeable. Of course, as they are practice nights during the week, perfection is not expected. And of course, it depends on the quality of the fittings - 1910 bells are far easier to ring well than something from 1724, say.
Mind you, you're not wrong about bellringers being into beer... a triple venn diagram of beer fans, train enthusiasts and bellringers would have several overlaps.
Bellringers don't have the same persuasiveness as the railways in terms of the noise being linked to something of value to the whole community. At the same time, the same principles apply - the trains and the bells normally came before the current occupants!
