Thought I would pass on what I found.
22 Hornet - Two things - First, the little nib at the front of the bolt guide was too tall. This is the piece that lifts the bolt guide catch as the bolt goes closed. Being too tall, it was trying to lift the catch farther than it could go (before being stopped by the underside of the bolt guide). This caused a springy binding action during the last 1/4 inch or so of straight forward travel (before bolt rotation). The touch of a file solved that problem. Second, the extractor was binding on the lip of the barrel. The barrel is cone (tit) shaped at the entrance to the chamber. This is a bit difficult to describe, but the edge of the cone should be thin and recessed slightly where the extractor travels (in order to let the extractor catch the edge of the rim, which is small on a hornet). The cone edge was too thick. The leading edge of the extractor would catch on the cone edge going closed. The oversized edge would also hold the extractor away from the case rim, such that a sticky case would not be extracted. I very slightly rehaped the cone edge with a Dremel and a small diamond bit. I also put a slight bevel on the leading edge of the extractor. She works slick now, and extracts properly. Both of these problems would probably have solved themselves with time, as the gun broke in, so to speak. This one had spent its life in a closet and had barely been shot.
30-30 - This an old well used one. The bolt drags over its entire stroke, as if it is too tight. I tried the 22 Hornet bolt in it, same problem. So it is the receiver and not the bolt. Have tried lapping compound and careful polishing, to no avail.
