I now have a Remington 700LSS in 300 Ultra. It sucks!!! I have owned it for about four years and have shot it nine times. I also have a Sako 338 Lapua that I have shot and taken much game with. I am left handed so I am ready to part with the Lapua and have built the "LONG RANGE" rifle. Do I build the 300 Ultra, 338 Ultra or what options do I have for a lefty Lapua? What is you "ULTIMATE" long range round?
