That is nuts.... Accepted level of pork fat in sausage and pepperettes is about 20-25%..... They just need to fat it up enough to get it in the casing, not dilute it..
That being said, if you are happy then all good... But when l butcher an average n size deer here myself and bring in about 45 pounds of boneless meat after taking my roasts and steaks I get about 55 - 60 pounds of sausage back and it costs me about $120
I believe it all depends on the ratio that the butcher uses. Some butchers around here use a 50-50 or 70-30 ratio. I know one butcher that buys the big hams when they go on sale and uses quality pork, not just fat and scraps.
As long as you are happy with it two dogs.... I personally wouldn't want to dilute my venison that much, but to each their own.... must say I wish I had the quantity you do.... lol
this place has been in business for many many years and most folks around agree that it's the best darn place around these parts for quality stuff. They are usually booked solid for a long long time after hunting season. Moose, elk everything goes there. I took my venison in 4 weeks prior to the new season. Beat the rush, so to speak!
