Back in the 1990's US Army used Fish & Wildlife Officers to cull deer on military installations. Majority of the shooting was performed at dusk using .243 rifles. Countless deer were killed and processed for local food banks. Yes, the .243 cartridge is a reliable deer killer. As a side note, now the culling is performed by licensed hunters using archery gear or shotguns. The hunting can be quite good depending upon the Army Base. - Sherwood
