What do you mean by lots of rounds? I have over 6500 through mine, and countless dry fires. The accutrigger is getting worn out, I've replaced the ejector, spring, extractor, and the detent ball in the bolt. The barrel still shoots good, but not sure for how much longer. Bolt lift will improve with use and cycling, it'll also get smoother. I never had issues with ejection until recently, parts do wear out. Replace them as needed.
If I were you, I'd look elsewhere for a left handed rifle. I've been down that road already, and I wasted a lot of money. There really isn't that great aftermarket support for Savage, and it's even worse in LH. Tikka and Remington come to mind for good aftermarket support.
