I bought a youth model .243 for my boys.It was a pleasure to shoot and after seeing how it performed on deer I went out and bought one for me. A Rem 700 SS Mountain rifle with a zeiss conquest 4.5x14x4mm. I'm comfortable taking deer out to 300 yards easy. I believe it is adequate for 400 yards , I just don't practice enough.

I shoot remington core lock when hunting in NC. I will use Federal premium tripple shock when I head to CO for mule deer
