ORIGINAL: Painted Horse
I bought a 270WSm in 2002 when they first came out because a friend did so well shooting Moose in Alaska with his 270WSM.
I have shot numerous elk with my 270WSM, Everything form 200 to 500 yards. It's usually Bang/Flop
I use a Barnes 140g TSX over 73.5 grains of MagPro. I shot a Spike two years ago as he faced me. Bullet entered base of neck and exited just above the tail. Almost the entire length of the elks body.
The first year I had the gun prior to working up a load. I used the factory 150g bullets and shot several Cow elk.
My buddy bought one and uses factory loads and has shot several cow elka nd a nice 374 bull this fall.
I've got a 300 WSM and several 30-06 rifles and they stay in the safe since I bought my 270WSM. No need to buy another gun just to hunt elk.
Always a good reason to buy another gun. But you don't need to unless you want to.
What factory 150gr. load and bullet you was using? I have been shooting 150gr. Winchester Power Point ammo out of my 700xcr 270wsm. It has been accurate and chronographed 3200fps. out of my gun. I haven't taken any animals with it yet. Next Sunday my doe deer tag starts. I can not wait to touch the trigger on a animal.
