I'm looking to find a good caliber/gun for my son (11 years old) to start deer and antelope hunting with that we can reload for and allow for the gun to "grow" with him.
My son is a prairie dog killing machine with his 223s and 22-250 out to 350 yards and he took his first deer this year with his 223.
I'm just looking for something that he can use now and then I can reload a bit stouter as he grows.
Any suggestions? I'm considering 243 win, 6x284, 6xc, yet any other good considerations
Thank you for the help in advance.
