Yes. I used to stuff off of my grinder and it was very slow.
I purchased a 5 lb sausage stuffer online for less than a 100 bucks and have been more than pleased.
Get the kind with the crank and not the horn type.
I have found the 5 lb large enough for everything that I have done so far.
I process all of my deer meat and make a few different sausages each year.
I found one on ebay for $90.00.
Mine was made by Buffalo products.
Good luck. Once you stuff this way, you will never go back to stuffing off of your grinder.
