...I have a Sako 75 Stainless Synthetic with Magnaport in .270WSM that shoots .5" to .75" at 100 yds with regular ole Nosler Custom Ammo using 140 gr Accubond. The caliber in this rife feels like a diet .243 and I've never recovered a bullet...shoots extremely flat and has enough energy to easily handle anything out their in North America excluding the big bears up North. Of the WSM calibers, this one has been the most popular according to an inside corporate guy just South of me in Springfield (Bass Pro Exec) fwiw.
