I shot my first deer with a 243 win and consider it the starting point for deer caliber selection. For most deer hunting it is fine. Are there better ones to pick from, you bet. Purchasing a 243 is an excellent way to pass a rifle down to a son/daughter ect. Good luck and happy shopping!
Passed mine down to my daughter, so that my grandchildren can learn to hunt. My youngest son used the rifle to kill his first deer.
We use Remington Core-Lokt in 100 grain and trust them implicitly.
