I have had a couple of these over the years they are ok but picky about what they will feed and bad to gall. Tuning the extractor along with polishing the feed ramp should clear up any feed issues. As to the galling the best answer I have found is black ice coatings black teflon www.blackicecoatings.com. Lee is really nice guy and comes highly recommended. I do not know the pricing but I have heard he is very reasonable. Hope this helps.
