I've only ever had 1 issue with a feed in my 93r17, And that was because the 2nd mag i purchased doesnt like to seat completely all the time. With the bolt lever up and bolt pulled back, the magazine loads fine. It takes more effort then it should to release it. But no errors in feeding.

Are you sure the magazines are seating all the way up as far as it should go?
if yes see this: http://savageshooters.com/SavageForu...c,30881.0.html

if you can't modify the magazines to get it to feed properly, Savage will be the people to ship it to.
Goodluck. Matt
