Last year I ground probably 100 plus pounds of moose. This year I am having major issues. Our grinder is only two years old and it isn't the most expensive one (only paid $200 for it) and it worked fine last year. This year it keeps clogging on sinew. I know, I know...Cut the sinew out, but even on the back hind quarter where no sinew is visable, I'm getting a clog. I took all my grinding meat and placed in the freezer until I could get some info. What am I doing wrong? My bull was a young one and the meat is pretty tender. Am I letting the meat get to warm, before grinding?
