Thank you for your answers, they have been a big help. I'll keep this thread going as I figure this stuff out. I spent hours on the Savage web site trying to understand these things, but it turns out that only partly prepares you for going into a big box store where they get their own custom models. I bought this at Cabela's, but I was in a Dick's Sporting goods and they also appeared to have special models. So I was going to go back there and do some more looking, it is nearby.

Wide Glide, I placed my order about 5 minutes before I saw your comment, but you reminded me that SWFA (swfa.com) sold their own rings so I put in a second order for them. They didn't have the Burris rings in short. I actually landed up calling SWFA this morning because I saw something else that concerned me on my order and I would like to say they were *very* helpful. The nice lady told me she would walk out back and repackage my 2 orders into one box and credit me the extra shipping. I chose their scope because it seems to have a reputation for being extremely reliable with a focus on that reliability more than features. One review said you could put it in your freezer and then drop it on a cement floor and it would hold it's zero, he actually did this .

Breeze, I used those numbers to figure out the heights and it looks like the Burris (sig) zee low rings would fit fine.

Darkker, thanks for the extra long answer. I will try to figure out what I have. I see now after spending more time looking at rails last night that they make a distinction for "F-Class" as opposed to other Model 10 style Savage rifles. I also see Savage "target actions" for sale at some of the web sites. My guess right now is that they only come in Model 12 rifles, but not all Model 12 rifles have these actions? I can't tell yet if "target action" only applies to single shot versions or if they include magazine versions too. I have seen target actions for sale that take a magazine but maybe they are standard Model 10 units? I am sure this confusion comes from the Savage marketing dept. not the engineers, sigh.

I know that at my skill level these things don't make a difference, but I still want to understand all this. In general an action that didn't have a big hole for a magazine would be stronger and stiffer. So I don't know if it's fundamentally different or not, but it is different. In my mind, an action that was made from thicker metal would be basically the same, use the same parts etc., but would be stronger while still being fundamentally the same.

Wide Glide, does "pta" mean Palma Target Action? What does Palma mean?
