personally I would not hunt with a gun that is 100 years old. That being said, if I did, I would go for an L.C. Smith, Ithaca N.I.D., Lefever nitro, Fox sterlingworth, or Parker. Also, I would be shooting a low pressure (not low brass) load. These are available from pollywad, on line. They are 7,000 psi loads and are made for those grandpa guns. Now if you move up a few years the field is much better. I would most definately look for an Ithaca/SKB 100 series or an SKB 200E series. The SKB's are really under rated and way under priced. The 200E was available in 12 and 20. I paid $1500 for each of mine. They have chrome lined barrels too so they can shoot steel. If you get into new guns, I would look at the whole line of CZ shotguns low price / high value. You could go on the cheap if you get into a Stevens or Fox model B. Here are my SKB's. They are my "go to" shotguns. The top gun is a 12 SXS and the bottom is a single barrel trap, I also have the mate to the top gun in 20, but it is not shown here.
Looking forward to your visit tomorrow Paul.
