Maybe I can help. I have the same scope mounted in a set of quick release Talley rings on my FN Mauser actioned 30-06. It appears you have a Montana action, but I can't tell if it is a long action or a short. I will give you some measurements that might help. Sorry, I have to use a ruler. My calipers are out in the shop, and it's raining hard at the moment.
The rings are spaced exactly 5" apart, outside to outside. From the front of the front ring to the front of the objective bell is 3 1/8". I have to position my scopes quite a ways forward on most of my rifles. I have only a quarter of an inch of tube left behind the rear ring. If necessary, I could pull the scope back in the rings about 5/16". That would leave you even less scope hanging out over the action.
This is just a SWAG, but as I sit here and look at your pictures, and look at my scope as it sits mounted in Talley rings, I think it might work. I hope the measurements help, and they make some sort of sense to you.
Let me know if I can be of any more help. Oh, by the way, this scope will work fine for the application you originally describe. That's exactly how I use mine.
