To add my .02 cents worth, I work at a rifle range and have seen 6 model 710's fail during my tenure, 2 had the firing pin break, 1 had the bolt fail to extract, 1 had the stock crack after the heavy recoil of a ,300 Mag, and 2 more had the bolt seal shut to where it would not open, the 2 bolts were later inspected by a gunsmith and were found to have some internal mechanisms just wear out. The 710's are unreliable rifles, unless you shoot under 2 boxes of ammo a year through your rifle i don't recommend the 710 to anyone.
It's probably true about if you shoot a lot that the 710 would be unreliable. Yesterday I shot a nice 8 pointer with the 710 .243. But as soon as I get my .30-30 set up with a scope, the 710 will have to be a back-up rifle.
