My arms are buggered and I have to shoot two handed---but pretty much every Webley pistol I own will hit a bottle cap at 7 1/2 -- 8 yards more often than not.
I took a Senior out tonight, that I changed the piston on a few days ago and is still settling in (over oiling) and by aiming at 7 o clock) was killing bottle caps even after a bottle or so of wine.
I do wish we could still get Milbro Caledionians as these seem to fit the Webley barrels so well and plink well.
I have done a thread on tuning the Tempest trigger. It is on here and on Dannys site https://forum.vintageairgunsgallery....pest/#post-233
