I saw recommendations to someone else about conversions of a double gun to rifle and I could tell you guys have been around the block and new what you where talking about. I am just delving into this and have built many guns of differing types but never a double (actually would like to hire some one to do the barrel work?).I am going to go big bore (really big 8 and 10 bore)I have acquired a very solid e.c. green underlever (no dolls head)back action lock in 8 bore (barrels are dented at muzzle ends) , now from everything I can gather this will be ok with black powder loads and round ball ? what are your opinion's or recommendations for someone to do work for me.

I was planning on practice on a ten bore upper lever Belgium(with dolls head) but not sure on this one ?
