first off I would NOT break the law and risk a trespassing and even poaching ticket, thats permanently on your record for a deer

yes, it sucks, but I've had it happen to me, same scenario only with a bow . Mortally wounded deer, probably a few yards into the corn, farmer/landowner told me and DNR no. Too bad but unfortunately it happens.

I'd work on the guy though. Go to him in the offseason and tell him you feel bad about wasting deer, ask him if he likes venison ? or summer sausage. Maybe suggest if he hates deer so much you'll gladly rid his property of them if he lets you hunt , worth a try. Or offer him summer sausage or part/half the deer you have to retrieve off his property in the future.
