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 ?

Chris,
Sorry to hear of this, could be many things from finding preferred pellet to bad barrel. Best diagnostic tool for PCPs is a chronograph. Chinese-made, clamp-on barrel style can be found on Amazon for less that $30, members swear by them. Determining pellet speed consistency can help diagnose problems. WM

If you head over to Amazon to check out chronographs, also search for H&N .22 Pellet Sampler Pack. This sampler provides 6-7 clear, plastic tubes of top H&N pellets. Samplers offer shooters a chance to determine which pellet a gun might prefer, without having to purchase expensive tins. JSB and other pellet makers offer samplers but I'd start with H&N. WM

Ok thank you but I have an another question I am new. To the pcp air rifle field what does a chronograph do and how do i use one I have a lot of different guns but I s don‘t really know how to use it

That is strange. I have an origin which I don't use much anymore, but it was always a tack-driver. Had no problem taking dove and rabbit at over 80 yds. If it's brand new, there could be a barrel issue or problems with air pressure. Mine really like JSB 18.13. Shot 3/8" groups at 50yds.

I honestly haven’t tried different kinds of pellets yet i do have a h&n pellet sampler on the way but as far as pellets I have been using crosman hollow points and they are 14 grain these are also the pellets I have been using to know birds out of Trees with my Gamo swarm 10x 22 cal so I thought it should work fine in this gun to But I guess I was wrong

You need to know how fast it is shooting and how consistent the shot string is.
For example, my guns have a 3000psi capacity, yet they all work best starting around 2600 or so. From 3000 to 2600 the shots are lower power and not very accurate compared to the sweet spot.
I use the $30 chrony. It clamps to the end of the barrel and measures pellet speed. You are blind without one.

I just fixed the scope today I am not used to only having a left and right turn Nob and up and down turn nob so what i found here yesterday was that I had the scope completely side ways I just fixed the scope

Clamp to end of barrel, turn unit on, shoot and read the number. I will find a link.
What you show is an actual chronograph. They don’t work in my low light life.
The China device uses LED to measure the speed and is not dependent on good lighting. And you will not shoot the device as it clamps to the barrel.
There are two kinds of people. Those who have shot their chronograph and those who are about to.
With your first pcp you have entered a whole new world. You now have e a gun that you can adjust to get the speed that the pellets usually like.

I added a link.
I have one that I can adjust to shoot 13 grain up to 21 grain. There is a big difference in adjustment between the two.
i have not had an Origin, but i bet its shooting those lighter pellets pretty fast. Others with that gun may speak up later.
Now that the scope is in the ballpark, shoot some more and see how the accuracy is.
knowing the speed is a big part of learning how these things work.

I have another question then after find out what pellet it likes and the speed that pellet going what should I do next because the is also adjustable hammer spring what does a hammer spring do

I am pretty new to pcp and there is a lot to learn. I have not uncovered the tip of the iceberg.
Well see, that is part of the adjustment. Yesterday I was trying diff pellets in one of mine. I was shooting 13.43 grains at 935 fps. Smokin….i backed off the hammer spring tension a little bit and that brought the speed down closer to 900 and the accuracy improved. Most of the time pellets like to be just under 900 to get good accuracy.
Your gun is unregulated so the pressure you fill to will matter.
Example:
My Mrod has a max fill of 3,000 psi. But the sweet spot starts about 2,600. If I fill to 3,000, it’s too much pressure for the hammer to keep the valve open long enough for a full power shot. So shooting from 3k to 26 k is a waste of pellets as the are too slow for the scope adjustment set at higher speeds. So I fill to 2,600 and shoot down to 2,100 or so. That keeps things consistent.
I don’t know where yours will work best.
So if you see that it’s shooting those Crosmans say 950 or so, you my want to back off the hammer spring to bring the speed down closer to where it may be more accurate.
It is a balance between fill pressure and how hard the hammer hits the valve. Hence the China device to tell you what is happenin.
