Anybody know how many shots in 177 you get from the longer cylinder.

And how many are in the sweet spot?

Is it worth the expense of fitting the longer cylinder, do you think?

Is it possible for an RFD to get hold of one of the longer FAC barrels to go with the cylinder, so you don't have to buy a thin silencer to clear the cylinder with the normal sized barrel?

Replies gratefully received, especially from those with personal experience.
