Re: short barrel for long ranges
I have an 18" .308 Win. that is shooting MOA or less to 700yrds right now. If I play with the loads a little more, I might be able to tighten up some. Your 20" in 243 with good hand loads will get you all the accuracy you need. You may have to do some trigger work and stock prep. Make sure the barrel is free floated and the trigger is light and crisp.
