DaveJ has given you the best advise yet, don't skimp on your ammo and use a bullet that is designed to shoot a big animal. You will never go wrong with a nosler partition but the newer copper bullets will out penetrate them. Barnes x-bullets and hornady GMX are great choices in the 270. When I first started deer and moose hunting the only rifle I had was a 270 and all the experts told me it was too light and I should get a 308 or 30-06 , so I asked how their 308 shooting a 150 grain bullet at 2850fps was better than my 270 shooting 150grain bullet at 2900fps. I'm still waiting for the answer to that one, and I still haven't found an animal in Ontario that was too big for a 270 and I have a lot bigger guns now that won't kill them any better. If you shoot the 270 well don't hesitate in taking it just make sure it's full of the right ammo
