Meatballs attempt number ?

I continue to try to perfect a meatball recipe. This time I did ground beef, hot Italian sausage, fresh parsley, fresh garlic minced, parmesan cheese, fresh bread crumbs, milk, ricotta, 1 egg, beef base, onion powder, Italian seasoning, pepper, salt. The taste was pretty good but the meatballs were coarse/tough. Not dry. But coarse. I wonder if I get a meat grinder and grind them a second time if they would be more tender.
