First off, anyone that knows me knows I'm a diehard big gamehunter and 7mm fan. My cousin works for Browning and is telling me great things about the WSM's and even got one for himself. I'm about to get a new gun for the collection with my boys in mind (soon to 12 and hunting age). They will be chasing mule deer and elk. Now I'm an elk hunter and I'm not a huge fan of a standard 270 when hunting them. I've killed elk with one myself, but "prefer" the bigger cals since Ihave them.

My question is what are people's opinions in general of the 270 WSM for elk. Is the added punch and velocity over the standard 270 worth it? Does it give you a more reasonable "bigger" game rifle than the standard? If I had my way, I'd just get another 7mm, but I'm open to technology and change. My cousin knows his stuff and I'm leaning on getting the 270 WSM, but curious your opinions.

P.S. I'm a hand loader, so I'd be working up a load with a 150-160 gr bullet in mind.
