After multiple affairs with various magnums over a span of a couple decades I bought a .270. It did everything the fire breathers did, but with less drama, on my end of the rifle anyway. Only problem was I couldn't bring myself to hunt with the high grade walnut the gun was stocked with. It got replaced by a stainless synthetic .270 WSM. With 140 gr Berger VLD's it is a tack driver, and that same bullet laid a cow elk low just last week.
I have guided for over 30 years and was licensed as outfitter for 9 so I've had the good fortune of doing a bit of elk hunting. My experiences have led me to believe that the ol' .270 is one of the best elk cartridges available, reason being that anyone can shoot it well, and well placed shots is what kill elk.
