RE: Question with the .270
The ideal situation would be if you could shoot a few calibers and see what level of recoil is too much for you...
The .270 is a great deer caliber, my bother and his son both have one, the problem is, they don't like to shoot as much as I do so I sight them in for them...Both are pretty experienced hunters, but they don't like recoil and both admit it...
I'd also consider a 7mm-08 and a .243...My other brother has a 7mm-08 and it does kick a bit less than the .270 (I sight his rifles in as well...)
I shoota .243, the beauty of that caliber is that I also use it for crows, groundhogs, coyotes, etc., so I shoot year round...I go to the range and shoot a box of bullets and think nothing of it...A couple of other advantages is the low recoil so you never lose sight of the deer after pulling the trigger and you can also shoot it from your off shoulder...It's tougher for me to shoot a .270 left handed (I'm a righty)
and keep the scope from my eye...
