Mikewareing; I have to agree with you on the Webley MKIII; I've owned a few and still have one and they are definitely an open sight rifle. Put a scope on and they show how poor the group size really is at ranges beyond 20m. In fact a shed load of older rifles, BSA's etc, don't group well very far out. Having said that with open sights they can do the job and a delight; especially the much much older Bell target brigade.

Scope even 80's rifles and they struggle which is why they need tuning to get the best out of them. I shoot basic tuned FWB Sports but, though they shoot very straight, its not easy and I keep my distances respectful. I sold on most of my collection because I realized I was an accuracy junky and most of the old rifles just don't deliver. However, I have a full Venumized HW77 carbine on its way so, yes, I'm still hooked on springers.

Not much beats a BSA Airsporter S or Mercury S for pure open sights classic shooting. Ergonomically they point and come to the aim better than anything; beats the Germans by a mile. But, you can't stretch the distance.
Theobens bluing just can't be beaten.
Walnut rules.

Modern stuff is very dull and if it has a spring still needs a tune. I don't own an air Arms but I'm pleased they are there. I'll have one. The rest I'll leave.
