I just bought an MDT 20 moa rail from cabelas (80 bucks) 2 days ago, and a set of Leupold PRW2 30mm medium rings (100 bucks)from a local shop. Both seem very nice so far, but only put about 300 rds through the rifle.
Kind of an impulse buy after work that day, Cabelas had heavy barrel mk2s on for 329. I have an older one that I really like shooting with a Bushnell 3-9 (DIP 0moa rail) but wanted to put another rifle together. I like the ergos on the Savage action.
Put a Bushnell Match Pro on it and after zeroing it at 50 it was doing some nice groups with SK standard +.
I haven't tried anything else in it yet, it was too much fun calling shots and dinging the steel targets.
"4th gopher, nose." I know 50 yds is not a great stretch but it was a good first day.
Edge might go to the DIP rail as it's shorter so you'd be able to use lower rings. The MDT is longer than necessary and I had to use medium height rings to clear front and back.
Just my opinion though, lot of variables to consider when fitting parts.
