RE: 2nd Caliber opinion: .270 Win.
The 270 is a great round, perfectly suited for the likes of deer. While I still own one and have used it to harvest moose and elk, I would not be so bold to say that it will kill these animals with ease just based on the bullet selection alone. Both animals have thick hides, large bones and muscle structure that soaks up the energy of a bullet. When using a 270 or the likes one must yes pick the right bullet but also be able to limit themselves to ensure a good result insue's...if you can do this honestly then the 270 will do just fine. However all to often in hunting the perfect shot isn't always presented and as such I prefer a bit more than the 270 can deliver. Not a knock on great round just my 2 cents.
To the forget premium give me a corelokt comment, I respect the game I hunt to much do take this approach...I won't use a corelokt for a deer so wouldn't even consider it on anything bigger.
