Alot of those 788's can outshoot alot of model 700's. They weren't "supposed" to be better than their more expensive counterparts but in most cases they were. You got a bargain. If you still feel like you've been shafted Ill give you your money back!
I drooled over one in my local gun store awhile back that was chambered 6mm remington. Went back in the next week with intentions of trying to talk them down on it a little and it had already sold. For $475
and it had no scope or rings
