Also not sure what loads you are comparing but it looks like you are comparing a round nose 30 cal to the spitzer .270. A lot of magazine writers pull that lame trick to promote whatever they are writing about in an article. A 180 gr 3006 load would still have 1550 lbs of energy at 500yds and a.270 150gr. would have 1376 lbs. The .270 would be shooting 4 inches flatter at 500 yds than the 06. This data is based on maximum loads in both calibers both shooting nosler ballistic tip bullets.
