Economy is right!
I don't know if they're "bad" but what a cheezy looking set-up. The only experience that I have had has been second hand. A guy that shot IDPA at my club occassionally used to have one. He made the grave mistake of double charging a handload in 30-'06 and the 710 completely disintegrated in his face. It tore the right side of his face up and over his skull like a big flap and broke his cheek bones, messed up his eye, etc. The reconstructive surgery was pretty amazing but you could tell this guy took a pounding and was lucky to be alive.
According to him, the 710 is not built to the same safety limits as a standard 700. He mentioned something that a 700 should handle about 120,000 c.u.p before spontaneously discombobulating. During discovery research for his case the 710 apparently discombobulated at around 110,000. He's not making a 60 Minutes case out this I guess, I have heard no more of what Remington did.
Is this bad? I'm not sure, just don't make a mistake when handloading!
For the money, I'd rather buy a used 700 or Model 70 and get something that's at least more pleasant to look at!
