My own experience with my 110, purchased over 10 yrs ago, was that my bolt seemed "rough" and possibly "sticky"...and it did get better over time...I actually sat in front of the tv one night, put on some work gloves, and worked the bolt as many times as I could stand...it did get smoother........It'll never be like my Steyr..but it is passable for putting another in the chamber. Very utilitarian, but not pretty or smooth....I would never call my 110 smooth.
