Ben,

You need to come to the next BGRC Lodi Wisconsin Match in October or to speak to Ernie Stalman of Badger Barrels. He owns at least one and would be the best person to ask. I never fail to be amazed by his collection of double rifles - he has some real beauties and is always happy to explain the intricacies of owning and shooting these guns to anyone who asks him.

Good hunting!
