270 too light for mule deer

[Redram]

I was reading a gun rag and it said a 270 and 270WSM with a 130 or 140 grain bullet was not a good choice for mule deer past 200 yards. I tend to disagree with this since, they praise 100 grain 25-06 and 257 weatherby as IDEAL. I am heading to New Mexico with a 270 wsm with 130 ballistic tips and 140 accubonds and have the upmost confidence with either load. Am I crazy or are they pushing a different bias?
