R H Clark,
A word of caution with the Leopold 2.5X is that it has a very long eye relief, 4.9" if memory serves me correctly. With mine on a long action (JC Higgins 50) I don't have enough tube length to mount the scope reward enough to get the scope objective where I would prefer it, I have to stretch my neck a little when mounting the gun. Now this is may only be a problem on a long action, if your Montana is a short action it may not be a problem.
I like the long eye relief because I am naturally a stock "crawler" when shooting at times, and have the scar tissue to prove it.
