I've never owned or shot a Remington semi-auto, so can't really comment on them other than I've read a lot on this and other forums about jamming problems. Just do a search and see what others have already said.
If you really want a semi-auto, save up a few extra pennies and get yourself a Browning BAR. There are none better!
As far as accuracy is concerned, a bolt action, in general, is more accurate than a semi-auto, otherwise you would see semi-auto's in the benchrest competitions.
However, as far as Browning BAR's are concerned, don't let anyone tell you they aren't accurate! I've got a BAR in 30-06 shooting 180Grn Sierra Game Kings on top of IMR-4831 that averages .58"CTC 3 shot groups at 100 Yds and groups with the Nosler Ballistic Tips average just a hair over MOA @ 100Yds. (Actually 1.3"CTC) My 200 Yd groups with these bullets are averaging in the 2-3" CTC range but I'm certian that's more a factor of my lack of practice @ 200 Yds.
Now there are probably a lot of bolt action guns out there that can shoot better groups than that, and if you're looking to get into benchrest shooting....go get you a good bolt action. However; if you're getting the gun for hunting.......Well, I'm getting consistent MOA or better groups with my BAR, and I guarantee you that the game you shoot won't be able to tell the difference between a MOA (or better) shot from a semi-auto and an Sub-MOA (or better) shot from a bolt action.....LOL
