Scopes are my kryptonite. For whatever reason as soon as I have to adjust a scope I lose 50+ IQ points instantly . I spent almost all day yesterday and half of today trying to sight in 3 guns at 34 yards. It was an absolute mess. I got 2 on point but the third went from not too far off to looking like it needs some serious shimming, so I don’t know. Hopefully you find that right pellet. I know my 2 hunter models are pretty sensitive to seating depth. I can lower a group at 25 from 1-2 inches to about a quarter with the same pellet just by figuring out what depth to seat the pellet. An example would be CPLs in my wife’s elite. Sit them flush and you’ll get an inch, seat them deep but uniform and you get a quarter sized group with several in the “same hole”.
