I have a G33/40 Custom that is exceptionally smooth and slick for a Mauser action.

The worst ones were the old Parker Hales, made from Spanish Santa Barbara actions, and many of the Brno 600's. In fact, despite the currant idea of the old Brno rifles (which have made them out to be of top quality despite the fact they were an economy Soviet block import at the time)I don't think I have met a Brno of any era that didn't have a feeding or extraction issue of some kind and that includes the much lauded-ZG47's and Model 21/22's. I decided a long time ago I wasn't wasting my time on Brno's any more.
