The 243 is a great round that will do the job on deer. The 770 is the revised 710. I'd stay away from it.
I agree on both things. As a back up to a backup the 770 mght be considered but otherwise... If you're serious about buying a decent rifle don't bother with the 770 (or 710). I know, I know...it's affordable. Well, you get what you pay for is verrry true in thiscase. Maybe look at the Savage line.
