I have limited experience with Fairshake's design, having only shot a handful of bullets that Jack Kort sent me to try out. I have not tried the 43-220C design, but I HAVE used Jack's 43-215C with the large lube groove and the crimp groove. I purchased the mold after communicating with Jack about various issues. Some of those had to do with telescoping bullets when loading smokeless in my rifles. I had been using Lyman's 427098, which does not have a crimp groove. I tried a number of methods to prevent smokeless bullets from being pushed back into the cases, but with limited success. When I switched to the 43-215C (and stay on top of case length) I have had near perfect results. I know that others have been able to make bullets without crimp grooves work for smokeless loads, but it was a great frustration to me. I liked that bullet design enough that I incorporated some aspects (large lube groove and "hidden" crimp groove while maintaining the original nose profile) into molds for the 45 S&W and 56-50 Spencer with equally great results.
There. Perhaps slightly more experience with these bullets than Coffinmaker, but not much more to add.
