I own all 3... (243 wssm, 243 winchester, 270 and 2-308's) and the 243 wssm is my favorite round of the 3... It drops them dead in their tracks and is great for long range... (put one through the heart at 313yds this season) the 270 and 308 are great rounds also.. only problem with the wssm is ammo.. winchester is the only one that makes it... but its good ammo, just hope they never stop making it.. On a side note..... of those 5 guns i mentioned 1 is a 06' model 70, one is a pre64 model 70, one is a ruger, one is a sako and one is a kimber..... If you can afford it buy a kimber.. best rifle out of the box i have owned.
