Gunwriter Dave Petzal says 150 grain bullets are best in the 270. I have always shot 130s. Over the last year or so I have tried 150s in my 270s (I currently have four) to find that 150s do shoot well. The most accurate factory I have tried is the Federal 150 grain round nose stuff, oddly enough.
This is interesting, because to my knowledge (and I've known Petzal well for a long time) the only elk he ever dared to shoot with the .270 was taken with Winchester's 140-grain Fail Safe factory load....
