I assume you know that letting all that meat warm up that much is fairly dangerous, right?
Your meat AND your grinder should both be as cold as possible. When I ground meat in the past the grinder lived in the freezer until I needed it.
The meat was already ground (at the time of butchering), I only let it warm to soften it up to mix better. And I think the word dangerous is a bit overkill. We are talking about a an hour process, two at the most from 34 degrees to oven.
