Recently run across this site. I love deer hunting and would like to get set up to be able to make 400 yards shots . I currently shoot a 742 Remington wood master 308 cal. (For the last 40 years) I am not confident enough with this gun to shoot that far and thinking about 7mm. I have started navigating though this site and am amazed with all the information and post . I am sure I will obtain useful information and may reach out for help when needed. Thanks for having me.
