I was hoping some owners of .25 vintage air rifles, Webley, BSA, Gem or whatever might be kind enough to post what velocity they find these large calibre examples capable of, together with the pellet weight used to determine the velocity. If you could say what sort of mecanical condition you consider it to be in that might help to compare like for like. For instance a resprung fully renovated example couldn't be compared side by side fairly with an example known to be in need of a new spring. I think it might be interesting to know how these vintage makes might perform compared to one another.
