Am just starting to load for two .256 Newtons (original Newton Rifles) with cocking piece sights - not expecting anything great from one with a rough bore. However, the other looks as though it has never been used. What kind of accuracy level should I be looking for.

Good question. Wondered about the hinged cocking piece peep sights myself vs fixed peeps.

Most all actions are slightly different, so when cocked, how much, if any play is there?
If you had a solid lockup at the range, or for a range out the dining room window if possible aligned on a target of some sort, mark on a tree or whatever, say 50yards distance, you could feed (cycle) dummy rounds into the action and looking through the sights, see if there was a change in the sighting, between cyclings of the action - or between actual shots at a range - or merely test it by shooting.
Due to differences in rifles, there would be nor could be and guarantee or possibly and average of accuracy given - the accuracy of the average would be subject to the # of test rifles, would it not.

I'd have thought that if the action is still tight (and it sounds from what you say that it's in new or near new condition) then the sights will be absolutely fine.
I think, for all practical purposes, there would be no quantifiable difference between the utility of a receiver sight and a cocking piece sight when used on a hunting rifle.
However, if the rifle in question is being used for long range target shooting, a receiver sight would usually have greater utility because, more often than not, it will come with a wider range of adjustment for windage and elevation - and in many instances will be much more easily adjusted.
That said, the actual mounting location of the sight (on the rear of the cocking-piece), should have little or no impact on it's general usefulness as a sight and indeed it could be said to be arguably better.

I have a cocking piece sight (Rigby style) on my DWM 7x57 custom and it is absolutley as accurate as low powered scope. It goes without saying that the type of target needed to do this but there is no reason not to expect good to excellent accuracy from a tight actioned rifle. A 200 yd kill on goat sized animals is easily expected as this one was (and with a cast bullet as well.)

Damn fine looking rifle Gruff and in 7 mm Mauser too. Looks like a hell of a lot of fun.

If you'll look in an old Rigby action with a cocking piece sight, the top of the sear is notched.
The corresponding face at the bottom of the cocking piece is pointed, so it fits into the notch,
going to centre every time. If the sear is a reasonably close fit in the slot in the bottom of the
action, the sight maintains windage very well.

I don't know much about the Newton rifles, but I remember reading that quality Mauser 98 rifles fitted with cocking piece peeps, had a pin or screw fitted to the bridge that would ensure that the peep was always properly aligned each time the bolt was closed.
I think Joel Dorleac gave details on this in a thread here somewhere. I tried to find it but couldn't track it down.
