I am having a lot of problems with trying to figure out why my umarex origin is not shooting on paper I have cleaned the barrel, I have tightened everything I could have found to tighten and have put like 100 some odd 22 caliber pellets through it to get it sighted in and I can’t get it to stay shooting in one spot on paper what should I do ?

You for sure do not want to shoot too light or heavy pellets, i do not have this rifle but i would assume it can match my decade + old FX cyclone in power, so 15/16 - 18 grain JSB domed pellets should fly good, and probably also the JTS pellets ( domed ) i tried last summer in my Cyclone
If you grab some random cheap weird brand pellet, then you will not shoot that well, i for instance have never seen pointed pellets fly good in anything, my friend do have success with flat head pellets in some rifles but at moderate distances.
The chronograph, is a good tool, but you can also do it the old way by just finding the one or few pellets the rifle shoot well with and then just stick to those, and so not needing to tune / adjust on your rifle.
If you do get a chronograph, either shoot thru model like you posted picture of, or smaller attach to rifle kind, you will probably see that speeds in the 800 - 900 FPS range is working good.
Many of us still have a pellet collection so we have umpteed brand / models / weights of pellets to try in a new rifle, even if today many rifles are adjustable and so you have a chance of tuning speed a little and so maybe get a marginal pellet to shoot good too.
In a .22 15 - 18 grain is good middle weights today, though some tins will say heavy / jumbo heavy, the really light ones in general are just for old anemic rifles or rifles tuned down to have a larger shot count on a fill.

Chris,
Sorry for late response, can't always get back to computer. Struckat really offered solid advice, as well as others, hope it helped. In simplest terms, pellets are happiest at certain speeds, which equates to best accuracy, shoot too fast, or too slow, accuracy suffers. Most agree around 850-900 feet per second (FPS) is preferred. .22 pellets come in a wide range of weights so designers of your airgun most likely tuned for an AVERAGE weight pellet at 850-900 fps. If you shoot heavier, or lighter pellets, the FPS will change, possibly outside of what is ideal for accuracy. A chronograph will tell what FPS your pellets are traveling, a great diagnostic tool for solving accuracy concerns. WM

The internet is your best resource for information on the Origin .22 . There's quite a few videos and write-ups on it . From what I could find 18gr pellets put you in the 880 fps range . I would try some JSBs round nose 18gr pellets to start. You will probably get around 30 shots in the sweet spot. Without a chronograph your basically guessing where your sweet spot is but like Struckat said 2600 psi would be a good starting point . That's where most of my unregulated airguns shoot with the lowest spread in fps . The lighter pellets will probably be shooting 920 fps or more and your accuracy could suffer from shooting too fast . I did own a .25 cal Origin and usually started around 2700-2600 psi for my most consistent shot string of around 14 shots . Some of the videos will help you find out what pellets are grouping well with the factory tune . Your hammer spring is easily adjustable for lighter than 18gr or heavier pellets but you need a chronograph to find the 800-900 fps range . Good luck and have fun .

Mine was very accurate out to 75 yards with cheap Crossman pellets shooting at 850fps but groups were tighter with JSB. I don't recall what weight though.
I did have some POI shift but minimized that with a barrel band. I had to experiment wth placement though. It was most effective at about an inch from the forearm.
