Hi all, I have been offered the above rifle. Problem is, it seems they were produced in .22 short and long. The barrel is stamped .22 Cal. So does it cycle and fire both short and long or is it one or the other? How can I find out what calibre this rifle is. I live in the UK and .22 long is nowhere. I have a Winchester 1890 and that chambers .22 short only. The Lightning is a lovely historic rifle that I would love to own, so any help will be greatly appreciated.
