Both will work. My 7-30 is in contender (ported factory 14", minimal recoil, no muzzle jump) and I'm finding that with copper bullets I am limited to ~200 yards with the Barns 120 gn TSX (the lowest minimum expansion velocity in a light 7mm bullet available from Barnes). 7mm-08 would buy you a good bit extra range with increased velocity and options for heavier bullets. Soft lead core bullets that expand at lower velocities will undoubtedly work to longer ranges, but I don't know enough to speak about them. I will likely send the 7-30 down the road shortly to finance a custom 223 barrel and stick with my 30-30 and the Barnes black tip bullets for deer. I've also started hunting with the electronic ear muffs for hearing protection and pull them down over my ears if the shot allows.
As for barrels, Bullberry, MGM and SSK are popular and respected sources.
