Don't have a 243, but I do have a 6.5 x 55 that I just love to shoot. Also have a 375 H & H and a 505 Gibbs. If I was to show up with my 505, what would you say for a second rifle. I shoo mostly Hornady's in the 375 and they shoot pretty good. I gather that you would not like me to show up with my 303 smle though!!
