After some research I found out this zouave is proof marked AB which makes it a 1976 date of manufacture.

Ok, I had a brain**** today and ended up bringing a couple guns home after doin some trading. Gun one is a new single shot 243 ready to go for my 10 yr old son. Gun two is a Zouave. Now, I have only handled one zouave before and that one belongs to a friend that does reenactments. This one looks new, looks like it has been shot just a few times and not a scratch on it that I have noticed anyway. So, since I'd a dunce when it comes to what the specs are I could use some help on it. The markings are Armi Jager Italy on the barrel. Not sure if it's a good one or not and I don't know what the twist rate is yet but, I just planned on RB anyway. How accurate can these be with RB's, and what kind of advice can you all give me about it?
