I have an opportunity to pick up a 30-338 sporter built on a 700 action for next to nothing. (less than $300) What are pros/cons of this caliber vs. traditional calibers such as 300 Win Mag or the new short mags?? Oh yeah, this comes with RCBS dies and I have been reloading for years, so the wildcat issue is no factor to me. This is a very nice looking gun in it's sporter configuration. TIA
