Use whatever, just hunt from ladder stands and shoot downward.
This is the realistic best answer.
One loud report, regarldess of what its from, is much better than any bullets or wounded deer stumbling or tumbling into their back yards.
Shoot from a stand, always aim into the dirt, hunt the property like you have a bow and be glad you can use a rifle. From above hit spine into the vitals and they are DRT regardless fo what you use.
Were I you Id bloody each gun on the new property.
An then start loading cast bullets for your 350 or for your new 45-70 falling block or rebore dads old 38-40 to ... something.
