Looking at a #5 Remington action rolling block in pristine condition. What can you tell me about this model? Have shot '93 Spanish Mauser in this caliber in the past and like the round but understand that the rolling block is not a really strong action for this round. The bore is perfect, shiney and smooth, and there is even some case hardening left on the receiver--any clue as to what should be paid for such a beast?
