I have a rem700 in 30-06 which is my main rifle, and I have a rem700 in 223 that is going to be my shooter/ coyote rifle. The feeding/extraction is not a problem at all on any 700 I have ever personally seen or owned. I will tell you about a real problem that is remedied with a modification that costs a bit of money though.
I was hunting with my 30-06, walking out at the end of a morning hunt, when I saw a grouse. I put the safety off slowely as to not spook it (I head shoot these with my hunting rifle when the opportunity arises), I squeezed the trigger, and the gun didn't go off. I pushed the safety forward further only to have the gun discharge. I'd used 700's for a long time, and never had this happen, but I tried it at home (unloaded of course), and this would occasionally repeat! I loved the rifle otherwise, but this was either to be fixed, or I needed to get rid of the rifle. a gentry 3 position safety cost $400.00 installed from Ralph Martini, and I won't own a 700 without this conversion done. It turns a $750.00 gun into a $1150.00 gun, but I dont even concider that as I like the rest of the action very much.
