Maybe you've encountered more issues with the 710 than other rifles....that may only mean there's a lot more of them out there. I was told by a salesman at one point that they sold probably five 710s for every Savage 110 for probably no other reason than the Remington name, so even with a relatively equal rate of problems, you're going to necessarily end up with more 710s in the shop due to the numbers being sold.
There are a great many more model 700s ,model 70s,A-bolts,and Savage bolt action rifles being used than 710/770 rifles,yet I have never heard so many bad reports about any of those rifles.There seems to be 3 or 4 bad reports for every good report about the 710/770.I have used all of those models,and all were much better made with much smoother actions,and none of them had pressed in barrels.
