Ed,Jumped out to shoot a card at lunch…
….so close to a 190 with Crosman pellets. Mild breeze, so I was adjusting for wind as I only shooting 680fps.
Check this out - 189 7x with Crosman Premier Ultra Magnum 14.3g pellets using Weihrauch HW110 .22 !

Not sure if you saw my post from last night. Here it is again ( I included some edits), but I did see your earlier post explaining your barrel and HST changes and mods. Read on....

Re. HW110 - I have the HW100 .22 carbine (410mm barrel) and it shoots both the JSB 15.89 and 18.1 pretty well. In looking at one review on AoA, the user liked 820 FPS for the 18.1 and 900 FPS for the 14.35 pellets. I have done a lot of tuning and Chrony work, and my .22 seems to shoot best in the 845-850 FPS range for the 18.1. At that tune, it also shoots the 15.89 at around 875 FPS. When my buddy and I tuned both the reg & HST, the maximum HST was around 895 FPS. So, a balanced tune for me was in the 95-97% of max HST range or 845-850 FPS, which is where it is right now shooting the 18.1.
What are your typical group sizes at 25Y? You should be getting five shots in a ragged hole at 20-25 yards from a solid bench rest setup with your HW110.
Have you adjusted your HST and/ or reg to increase the velocity for the JSB pellets? 650 FPS seems very low to me, and I am wondering if you might get better accuracy with increased velocity?
PM me when you get a chance and we should talk via phone.
