Since you arein Wisconsin, then anything is legal. As long as its open sights, orthe scope has no magnification and the bore is bigger then .40 caliber. I use two rifles with 1X scopes on them...Or I have a number of other rifles with open sights and RED DOTs to shoot.

That Omega should do you just fine. That is an easy 100 yard rifle for you. With a 209 primer ignition it would be water resistant. And with a good load, no Wisconsin whitetail would get away. As for other suggestions.. if you had a price range you were willing to spend it would help others in the group with your considerations.
