I’ve never seen a deer “run” with both shoulders broken more than a few feet… and that just hindquarters-driven plowing ahead. Are you losing deer or just having to find them? If, up to recently, they’ve been dropping in their tracks and now they’re not it says to me you’ve been breaking shoulders or spine and now you’re not. Have you been examining the bullet path after gutting and skinning them? As someone mentioned above, often well-hit deer don’t leave much blood trail, there are a lot of factors involved in whether or not you get a good blood trail.
