So I got a line on new in box, unfired Remington 750 .308. Priced what I think is a good price of $700. (no scope) What I'm not sure of is since it's a carbine, 18.5" barrel as opposed to a 22" barrel, is the accuracy compromised? Anybody have any experience with these autoloaders? Obviously I have read all about the predecessors and it's prone to jamming for a variety of reasons but I have also read so long as you keep her clean, she'll do just fine. I've always had an itch for one of these in the .308 or 30.06, but if I were to by one back in 2015, I don't think I would have selected the carbine.

Anything I should know about these rifles, and in particular, the carbine version?

I have nothing to offer about that rifle in particular but typically the shorter the barrel the less harmonics. The less harmonics the more accurate it is.

That's a good price
I've had 742's and 7400's and no problems with
functioning. Never had a 750, but it's supposed
to be better all around than the predecessors.

I had bad experiences with a pair of 742s a number of years ago. If you really want an autoloader, buy a BAR instead.

I think $600- $700 is a decent price for a 750 that is “like new” but has been used lightly. Brand new in the box, I would absolutely pay that. You might even be able to flip it for a little bit more.

People are afraid to buy them because they really are know for jamming, and most of the time that is a maintainence issue. They never get cleaned good and proper and are hard to tear down unlike a bolt gun. So the chamber eventually develops a little pitting and they have to be polished back out to work right, but that might effect headspace and then you might as well dump it. But that normally applies to older guns like the 742.

I think a new in box 750 is a score. .308 and carbine even better.

Barrel length in this case shouldn't hurt accuracy, only decrease velocity. As mentioned above from an accuracy stand point you may be better off.

I would not expect a whole lot of accuracy out of one but how much do you need? It is a deer rifle and should shoot good enough for that every bit of the point blank range of a .308.

Good deal.
