I ordered a Savage 116 FSAK in 338 WM yesterday from a friend of mine. He has two of them, a 300UM and 300WSM and both of them are tack drivers. Now I am looking at a 3-9x-40, either Nikon Buckmaster. Bushnell Elite 3200, or Simmons Aetec. Key features being 3 1/2"+ eye relief, wide field of view, and bright glass.
I appreciate all the input and wise suggestions. You wouldn't believe the time I have spent reviewing ballistics and reviews of the different cartridges. The bottom line was the 338WM was simply more versatile than the others. It was close but the 300WM doesn't pack quite the punch and 300UM is pretty limited on bullet weights with a lot of excess powder being burned. Excess powder means unneccesary recoil so the 338 seems to be a more efficient cartridge at the 4000 ft/lb power level. I have a 125 yd range in my backyard so the muzzlebrake shouldn't bother anyone but me and I will close it while hunting because extra clothes and adrenaline does wonders to reduce felt recoil.
The best part of this whole thing is if the 338WM isn't for me I still have the trusty 30-06 to do the deed.
