Northern meat saw and deer ?

"Hi Folks" Ok...I am the "QUEEN" of deer cutting here!! LOL After a few years of paying to have our deer processed we began doing our own due to inferior processing and cost. We have a plain old hand meat saw bought from Cabela's and a Oster electric grinder. [ The nice thing about the grinder is it also works real well as a stuffer.] We normally get between 6 and 10 deer a season. We trim the meat VERY well....that was one of our big complaints when we paid to have them done....a bunch of grisel/huge hunks of fat/tallow etc. We don't add any fat at all to our burger and it holds together just fine and tastes great! [ Plus it's good for you!] The only time we add anything to our venison is when we can it.....I add one strip of bacon to the top of each jar to give it a little fat and it makes the BEST gravy!!
