What are you planning to shoot with your 270? The Winchester 150gr Power Point is widely considered a great load for the money. Should be more than ample for deer.
If you want a really potent load check out the Federal High Energy cartridges. They are spendy, but they come in two versions, a 150gr Sierra Game King or a 140gr Trophy Bonded Bear Claw. How does almost 2000 ft/lbs of energy at 300yds sound to you? We chronographed the 140gr at 3300fps at the muzzle. Gonna use this load on moose in a couple of weeks. If the moose gods are smiling on us we'll let you know how it worked.
I would say the 270 is fine for moose. My cousin/hunting partner shot two moose with his this year. The first, a bull was at 80 yds, the second, a cow was 400. His first shoot went through both lungs. He was shooting 150 gr Partitions that I loaded up at 2650 fps. I am only SLIGHTLY jealous.
I've spent countless hours either on my hands and knees or bent over, messing up my back, looking for blood. One such instance I remember most was a hog hunt a few years ago in Mississippi. I had never shot a hog so when I poked a hole in this guy; I was determined to find him. Wearing snake leggings, I crawled on my hands and knees through the briars and the brambles and bushes where a rabbit wouldn't go. I found a spot of blood here and there but never the pig. And lucky for me, I didn't find...
