I haven't seen anybody here have a problem or take one apart and tweek them. The only time I have any feeding problems is with subsonic ammo, but you can expect that. I don't have any issues with the first round feeding. Only thing I can think of is that the magazine does not seat completely. Are you loading the magazine with the action in the open position(slid back) or the closed(firing) position?

Mine functions either way, but what I'm thinking is the magazine doesn't seat completely if loaded in the closed position.

Good luck. Might be a call to Savage deal.
