When it comes to smoothness and overall ease of movement, the action in my old Remington Model 700 that I purchased back in the late 80's is hard to beat. In fact, it moves so freely that if I forget and leave it open, it will slam forward or backward and practically surprise me. On the other hand, the action on the Howa 1500 Super Deluxe that I recently picked up has the zipper slide feel that you hear about so often these days. Of course I could be wrong, but I suspect that's because the inside of the action Howa action either wasn't polished as much as the Remington, or it has a steel coating that wasn't used back in the 80's. Whatever the case, I cannot see any advantage in terms of functionality since both actions work flawlessly at loading and unloading the chamber. If I had to say which action I like best between all my rifles, it would be the ones on my two Winchester Model 70's. They both seem plenty smooth but not so much that they move too freely.
