''Add weight to the end of the barrel of a break barrel and have an accidental let go when cocking and its a fast way to get a banana barrel. ''

I'm afraid that letting go to the barrel of a springer during cocking, with or without additional weight will give you a banana barrel.

BTW I think we can take a lead for HW themselves.....the 98 has a heavier shrouded barrel and are as accurate as accurate things go - saying that my old Mk1 95 .177 with the barrel weight excellent too.
