I can't open the picture here from the office, they have a lock on all gun sights except this one, so I can't see the gun. How ever I sold a Merkle O/U last fall that I had used in my first Safari. I used Norma Brass and Woodleigh 285 softs and solids with no problems at all. I think I still have a bag of new unfired brass kicking around, if you would like to buy them, I'll check to see if there still in the gun room. Dies too if your interested.
