Scopes do not stay accurate.

Im gonna get crucified for this but here goes.

Cheap scopes on cheap guns.

That's pretty much the issue right there in a nutshell.

Try it with open sights and see if they are accurate. At least then you can rule out the gun.

Good luck.

All Crosmans? I once owned a .177 Crosman Quest which was a Chinese clone of a Gamo 220 and I couldn't group with that gun either, even after adding a trigger insert that made the trigger bearable.

Disassembling the gun I found that the Gamo design "pivot bolt through a sleeve through a hole in the the barrel pivot block" was machined poorly. The sleeve in the barrel pivot block was a rather loose fit and the fit of the pivot bolt in the sleeve was rather loose. On top of this the hole in the sleeve was eccentric to the outside of the sleeve. This combination of poor fits caused the poi to orbit about the aim point as the "sleeve with eccentric hole" would rotate a bit when cocking the gun. Hole in part#21 was eccentric............

I don't know if the other Crosman offerings are better or not but I've never had to adjust my scope "36 clicks" to restore zero. Perhaps your scope erector mechanism is so off center {due to poor barrel alignment or whatever) that there is no/little tension on the erector spring which allows the reticle to get thrashed out of alignment with each shot.

Basically, if all 4 of your Crosmans are doing the same "poi shifting" I would suspect the scope if it was used on each gun.

I learned not to prop my guns up by the barrel ,
There is something about pellet guns and leaning the gun up by the barrel, Its a big NO NO ..............

Hummmm.....like this.........

I agree with that statement for sure.

Another point not yet made is that springers need a warm up period when shot from being rested more than a few hours. So ignore the first 10-20 shots then see what it's doing for poi vs poa.

Hummm......maybe not necessarily! Here are a couple targets with bulls shot a couple days apart using an oring sealed HW95 or R9.
LOL....I admit that they were shot at only 18 yards.......


I contend that most of the variations are the shooter swaying on a bucket resting the gun on cross sticks.

I personally tend to avoid "consistency testing" outdoors at longer distances because I do need a few "zeroing shots". I do believe that much of the "need warm up theory" is simply due to atmospheric conditions such as temperature, humidity, barometric pressure, and mybe even the phase of the moon (just joking with this one) unless that the gun is "slopped up with goop" or whatever.

Just my own personal opinion here and I do remember the days of shooting my .177 R9 with those "thin edged" HW piston seals that did indeed require a couple dozen shots to stabilize the poi even when properly lubed! Contrary to this I found that the newer design HW95 thick edged piston seal performs on par with my oring sealed piston caps!
