I have a little GEM pattern Diana smoothbore. Don't know what fps it does but it is probably in the 300's. At twenty feet it shoots maybe a two inch group, but I haven't shot it much and used wadcutters, not lead BB's.
When I copied the link using "properties" it somehow cut the "5" off the end of the address. Oh, well. Not much activity on THAT forum judging by the dates on those posts.
