Thanks greenwayjames, that is a brilliant insight from JB who I have the utmost respect for, and his guns.
Well if anyone knows what you can do with a BSA barrel it's John bowkett! I'm sure that information will help a lot of people but it also backs up what I had thought after checking a few BSA's I have. Ialso know a couple of world champions are using BSA barrels in German and Austrian guns.
Right it's getting the chop to Carbine length!!
