Bonanza,Marrakai, thankyou both.

I managed to find myself a damn gun,beauty, but it is 500 bpe not 577......much of a muchness isnt it really?

Anyway, now i wonder about well, everything about it.....luckily this caliber is affordable loaded, even more so if you home load, but I wonder what its like to use.....

I read that 577/500 story, but wasnt sure if the two have the same ballistics.

By the by mine is oval bore/invisible rifling.....i await the howls of horror!
