Yeah, just keep shooting for a few hundred rounds and see if anything improves after break-in. The factory radius on the bolt is too little in my opinion, another reason why they don't cycle so well.

You can grind and sand smooth a radius yourself on the rear of the bolt, but I just ordered a KID radiused bolt with my trigger I got from them. It cycles silky smooth now with no issues at all anymore. The radius makes the bolt "ramp" up the hammer at a different rate and spreads the cycle load out more.
