Nice No. 1's fellas
Good choice on getting a .243 again
I bought my wife a Remington model 7 in .243 a few years ago, and I have three 6mm's that have all been used for deer hunting at one time or another. One of them is now a dedicated varmint & predator rifle.
I've found the 85 gr Partition to be a great performing deer bullet for the .243
My hunting load for her .243 is the 85 gr NPT over a starting load of W760. Very little recoil and still plenty enough energy to drop a deer in it's tracks just as good as anything else.
Shot placement is the key whether you're using a .243 or .300 win mag
