Sorry to read about your troubles with your Savage. Hopefully it was just a screwup that made it out the door, it sounds like they will make it right.
Regarding the Zastava, (mine is the Charles Daly version that had the rollover comb Monte Carlo and a beavertail forearm) the only thing I don't really like is the trigger assembly. It took a lot of adjusting to get it to have a decent trigger pull and to get the safety work every time. I may replace it when I do the stock.
I do like the smaller action for this cartridge over the Savage.
