I believe they are better than the belted magnums. The best reason, IMO, is that they headspace off the shoulder, and not off the belt. Overall a cartridge is more accurate if it headspaces off of the shoulder, instead of the belt. I also belive a short action is more accurate than a long action. I also believe the shorter, fatter case gives better powder(consistent) burn.

I will not argue about here today and gone tomorrow. Who cares, I may be gone tomorrow.I would not buy the new cartridge if I bought factory rounds. However I reload and the price for reloading is about the same. Maybe a little more because I have to buy the brass. If I was buying factory ammo, I would buy a 30-06. But since I am reloading, I enjoy the extra performance. Tom.
