I've yet to have an issue killing geer with a .243 or even a .223 for that matter and I've killed a sizeable pile with both. The farthest I ever had a deer go after a solid double lung shot was with a 1 oz, 12 gauge slug and the second farthest was with a 200 gr. .35 Remington. No lung shot deer ever went close to as far as those two with the .243 or .223.... Guess 12 gauge slugs and 200 gr .35's must be inadequate for deer.
