I don't recommend the Remington 783.
1. It uses the same crappy extractor as the Marlin X7, and they are prone to failure (either breaking, or popping out of the bolt and jamming the bolt closed).
2. It's a Marlin X7 with some cosmetic tweaks, but for a higher price. (Remington wanted more profit, and their own name on the rifle; since their own 'budget' bolt action was crap.) If you want one, buy an X7 -- but remember that the extractor is a common failure point.
3. The fire control housing is probably the second most common failure point (same, exact assembly used on the Marlins). It breaks at the mount points, cannot be repaired, and replacement parts must be installed by Remington (and are not available for Marlins). Bad, bad part to have fail.
I have had many X7s, and still own a few; and I've spent a little time with production 783s. Outside of very special circumstances, I would never buy another X7, and will never buy a Rem 783.
The extractor design is a fatal flaw, and the weak fire control housing is icing on the cake.
My suggestion would be the Ruger American.
Better design.
More reliable.
Better customer service, should a problem arise.
I haven't given modern Mossbergs a chance, whatsoever, so I have no opinion there.
The Savage Axis should have a good barrel on it; but is otherwise garbage, in my opinion. (Just my opinion - plenty of people love them.)
