Any ideas. Having a new purdey single shot rook rifle 22 hornet built octagonal barrel & a new boss 5.6 x 50r over/under rifle similar action to boss 410 except well bolstered. Both guns will be dainty in size. Both guns will be scoped with Q-D mounts.I have 2 brand new etherington optical mk.1 .3 X. Scopes (mildurah Victoria) that I can use 3/4 tubes steel 13iches long. What would you use. I do like European scopes on English guns. The boss concerns me more to have a better scope.
