I agree with ctom sometimes heating up the molds will help as I do have an issue with another mold maker and we have to heat those molds up to about 250° to get them to shoot right but I've only had two molds out over 100 that we are having issues with one is by Jacob a note here Rick worked very hard with me on this mold so don't get me wrong on a beautiful maiden mold by Rick we highly recommend his molds. the other mold was by Lakeside this was a custom-built mold and we were having the same issues with it but by heating this mold up to 250 problem was solved due to the fact that the cavities in the protruding legs were very thin so it needed a hot mold in a very soft plastic to make it work right but I stand behind Jacob in Lakeside they are very good mold makers both of these guys have made custom-made molds for me and a course on Jacob I have designed a few of the molds on their.
here is another plastic bait from the mold that we were having problems with it you can see they come out beautiful.
