Here is a real decent gun that is improperly described as an 8X57JR. It's a post-war gun and is 8X57JR
S. It is a .323 diameter bore gun, so you can load for it using standard 8mm bullets we use today. The chambers are 2 3/4", so no worrying regarding shell length that some might do. The scope is a bit big, but it's a good scope for the period. I would call and ask for Floyd and see if he would go $1,800.00.
