Look at both the 338WM and 338 Lapua and compare.
300gr SMK with a .768 BChttp://www.sierrabullets.com/index.cfm? ... llettype=0
The 338WM will push a 300gr SMK damn near 2500fps out of a 24.5" barrel.
The 338 Lapua will push the same bullet up to 2700fps with a 27.5" barrel.
Obviously the Barrel length is not apples to apples, so this makes the WM even look better considering. It's been called the poor mans lapua for a reason. 10% less power, 30% less powder, and a fraction of the cost to reload. Because of this the WM barrel will last forever in comparison to the Lapua having a reputation for burning barrels in 1000rds or less.
Then plug in the figures into http://www.jbmballistics.com/cgi-bin/jb ... mp-5.1.cgi
At 800yrds the WM is only 22MOA of drop, 1777fps, and 2103ft.lbs on target! With only 1mil in a 10mph wind.
At 1000yrds 30.9 MOA, 1621.5fps, and 1751ft.lbs.
At 1590yrds you reach 60MOA which is at most peoples end of dial on scope even with a 20 MOA rail.
But at 1590 is when the bullet finally reaches 1100fps and may begin to go transonic, still carrying 800ft.lbs and is about 4times more power than a 38special point blank.
So to answer your question yes, the 338WM will destroy elk all day long at 1000-1200yrds.
I personally hand load 250gr TTSX Barnes at 2600fps for elk, and 300gr SMK for long range fun. I really only got my rifle finally dialed at the beginning of last fall, so this summer I'll have a lot more time to see what I can really do at distance.
I put one of the solid alum bedded Knox stocks on my 98 Mauser Kimber and it took ALL of the recoil away. Now it shoots like a 308 even with the heaviest loads. Best investment to tame the beast yet. And a real pleasure to shoot.
Reloading your own is the only way to make the round affordable, and get the full accuracy potential out of the gun.
