After looking and very much "going over" my new CZ Ringneck with a fine tooth comb, I've come to some conclusions and am in agreement with most here who have replied. I am extremely confindent that this gun will work for a .500 3" nitro-for-black, but nothing of a type with more pressure, without having to bush the pins, which is too much of a headache. So, I've decided to do something kind of neat to mine, and a lot simpler. I'm lopping the barrels to 24"(appropriately), adding sights(two in rear-like the pedersoli .72's) on a hand-made quarter-rib and front ramp, putting a silvers pad on, sling swivels(appropriately mounted on underrib and stock), and then load up with bore-size round balls with a roll-crimper. Will make a nice close range thumper for anything within 50yds. or so, and will double as a snake gun while in hog territory, which I have found is more than helpful. Plus, the ammo is almost free when made up with mold and empty hulls.
This should be pretty nice for an all-round "do-it-all" double.
In fact, I can't think of a more "useful" gun. Able to fire shot at the occasional bird, and completely penetrate (with hardened balls) just about anything in North America.
I'll post a pic here on this thread when she is finished.
Marrakai: I've been thinking of a vacation-if I can make it down there some time in the future, we should get together for some hogs and buff. By the way-every time I see that Greener of yours on here I get the "build it yourself" blues.
