Deer Hunter. There is no reason on this planet that your 270 would not be perfect for the hunt you have planned. The 270 has taken every game animal in North America and most of the big Deer sized Game in Africa. If you want a 7mmSTW, I would say get one but you sure won,t need it. If you can shoot your 270 well its all you will ever need for North Amercain hunting. To many Magnum shooters take shots well beyond thier capabilities to make a clean hit and a deer shot in the leg with a 416 rem Mag will go as far as one hit in the leg wit a 270. If a person can judge range well and know where his rifle hits at long range then the magnums will give you a little more useful range but a well placed 270 bullet will kill that deer just as dead and just as fast. I have a BUM shoulder too. I sold my last Magnum this fall and bought a 260 Remington. If my shoulder gets better I may go to a 270 Remington ADL synthetic.
