It's not just a "smaller bullet" that makes it a better round raf. Significantly less recoil offers 2 things. Better option for younger hunters or those that are highly recoil sensitive, and less muzzle rise for faster target re-acquisition. It's flatter shooting and you can get better performance out of a shorter barreled rifle. Fantastic selection of bullets from the 7mm lineup makes for a VERY good cartridge for everything up to and including Elk. I just had a .338fed built to replace my longer range shot rifle in 7mm08 for the simple reason I wanted a bit more authority on impact at 400 yards on Hogs. The 7mm08 performed well but I wanted something with some more "thump" to put those long range hogs on the ground quicker on "vitals" shots. 338fed is yet another cartridge based on a .308 parent case. The case is wonderful but the .308 is mediocre when there can be SOOOOO much more done with that case.
