[QUOTE="MontanaRifleman, post: 844276, member: 11717"] External ballistics is close, terminal ballistics not so close. I don't consider 20% difference close. Anytime you increase case capacity and powder charge you loose efficiency. A 7 RM is more efficient than a 7 RUM and a 7-08 is more efficient than a [B]7 RM[/B] [B](EDIT)[/B]. However, bigger is bigger, and more powder = more force. Bullet efficiency is determined by form factor and SD. My favorite rifles/cartridges are my 223, 22-250 and 6-284. They are "more" fun/sweet to shoot than my bigger guns. But I know the differences and capabilities & limitations of each. [/QUOTE]
