I agree my shot placement was not ideal my point was it seldom is a perfect world and I took the shot I had. I did have the sense to miss the shoulder and meat damage was minimal. I am not blaming the bullet I am saying their are better choices than a light caliber or worse yet light for caliber bullet.
The animal is in my freezer! I Know the 340 or a 338 would have fully penetrated in the same circumstances, I Believe the Sectional density is not something dreamed up by gun writers. And my point is again there are better choices than a .270 for Elk but if that is what you want, use a heavier bullet with proper sectional density.
