Home Forums Hunting & Shooting Deer Hunting Small area caliber choice?

I was part of deer cull in a city of 85,000. I used a 243 and shot 80gr. Remington ammo. 70 deer and not a one went more than 10 yards. Others used 223 with 55 gr. ammo with like results. If doing it again I would put a suppressor on the 243 and use the same ammo.
