RE: which .243 is the best
It depends on fit & feel.
What fits you best ? what feels good to you ?
Everyone has a preference as to make and model and I'm sure you'll get alot of opinions here. Go to some shops and hold em. Figure out what you like. A good starting point for your more commor rifles would be the Rem 700, Win 70, Browning A-bolt. For me... I like my Rem 700 .243 topped w/ an Aetec 3.8-12X44. It's my Coyote/back up deer gun. It has given me flawless service.
