As I recall from my teenage years, when I had an FWB127 - also in .22 - the sights were provided with three settings on the vertical: at 10m, 30m and 40m. I seem to recall trying these but the readings did not fit the distances implied. They were no more than an indication. Perhaps there was a further adjustment knob but even so, there were only three elevation settings. This was a problem.
I used the good weather two days ago to shoot my Webley Omega at 25yds with open sights. Since tightening up the breach screws, which connect the barrel to the body of the rifle - which were loose - I have managed to obtain improved accuracy. At 25 yds, I was obtaining very satisfactory groups between 3/4in - 1in and I think these could be improved upon, just. However, with a scope, these could certainly be bettered and I tested this option successfully, too. Moreover, at greater distances, the groups would benefit from a scope. Furthermore, a scope also permits a degree of holdover and hold-under, depending upon the distances and the range at which the scope has been set - ie it might have been 20yds, 25yds, 35yds or more. It is more difficult to make this holdover adjustment on open sights.
I have an early 1920s BSA Standard (operating at nearly 11.3ft/lbs) with open sights, where there is no choice available. I have decided to leave the Omega with open sights but might see if I can obtain a peep-sight for it. That leaves my FWB and Webley Longbow (both acquired this year), with scopes. This way, I can vary the choice between open and scoped, without having to remove a scope each time.
Using open sights provides greater satisfaction when one hits the target.
You might find that my solution is the best means of covering the choice - ie by collecting a rather larger range of rifles!
However, some considerable testing of different pellets is also necessary; the extent of the variance is quite remarkable.
