I've never tried a Simmons scope but have heard both good and bad about them. For $60 you'll find out! I don't think the new scopes are that much better than older vintage scope either. They just have more stuff built into them that may or may not suit you. Two of my Redfields I bought new in the early 70's. They both work fine and the only thing for me the new scopes have that is really an up grade is click wind age and elevation adjustment's. Mine are pressure but I wouldn't trade either for a new scope. I also have an old Weaver K4 with click adjustment's. Finally got tired of it doing nothing and put it on a 22 mag. Really is a nice scope! Old Banner I have I've had about 30+ years now and the only thing remotely new about it is click adjustments; it simply works! If the Simmon's fails on you, I wouldn't go get another $60 used scope and certainly not a 4-12x. You said a custom Interarms in 30-06? I'd look for a newer, probably new 2 3/4x fixed or 2-7x or 3-9x. Even with their shiny appearance they are classic power's. If you could find an Older Weaver k series, I could go for that. My K4 is an old steel tube scope and would be right at home on your 30-06, it's not for sale! In the cassic days, people were not so quick to sling bullet's into the next county to kill something!
BTW, that old K4 has plain cross wire's. Pretty classical!
