The 243 is gay and is for skinny little wimps that can't handle a REAL rifle....
Sorry someone had to say it after all those posts. I personally like the 7mm line over the 6mm line but have only ever seen one of the mythical 270's in person one time and I dared not hold it...
Mostly because the badass Marine that owned it looked like he would wipe the floor with me if I tried:)
