RWS diana 350 magnum shooting weird

Check those two screws that secure the rear sight to the breech block. That sight looks like it should go down further. It doesn't look like it's bottomed out ! The higher that rear sight is the higher your impacts are going to be. Those screws also come loose.

I am at a loss why your rifle is shooting high ! As mentioned before how's the barrel pivot bolt tightness?

tight, i think it is bent barrel after some more research. i think it is bent right at the breach block.

So now you have determined that the barrel is indeed bent upward at the breech block? You should be able to confirm by sighting along the side of the breech block and barrel and seeing when they are not parallel.
The most common cause of this is loosing your grip on the barrel while cocking or pulling the trigger with the barrel in the open position, both of which cause the barrel to snap up forcefully and slam the breech shut! The momentum of the barrel causes it to bend upward after the breech closes and stops pivoting. It's easy to do. Did this happen to you or someone else who was using the rifle? I also have an RWS 350 magnum and it takes a lot of strength and a firm grip to cock it, especially if you are shooting a lot and start to get tired or complacent with your grip.
This happened to me on my Beeman R1, another gun with a strong spring. I was able to use some wood scraps and a C clamp to bend mine back down. If this is what happened to you just before your POI shifted, your barrel got bent. Do a search on bending spring airgun barrels for a variety of articles and videos.
Good luck

thank you for the information, yes the trigger got pulled while the barrel was down, it didn't do anything for the first 2 shots they were really loud that was it, like really loud, 22 center fire loud, but after that they shot high, i thought it had something to do with it shooting loud, anyone know why it would shot loud?

I think it’s too late for my reply but you can fix it by yourself just take it apart and apply force to bend it back the steel has memory and will go back to the original form just go easy with the force , or I think you can send it to UMAREX USA to get it done.

I'm new to the forum, but I was reading through this one and felt the need to say, ALWAYS hold the barrel open with one hand after cocking and break barrel, even if it has an anti-beartrap mechanism. I learned this lesson the hard way with a Hatsan 135 .30cal. I cocked it but didn't hold the barrel closed. I don't think my finger was near the trigger, but something caused it to shoot while it was dangling open. I was surprised at how much force with which the barrel slammed closed. It was so much force that it snapped my wooden stock right in half. I was glad that my finger wasn't anywhere near the breech, and I was also thankful that the barrel didn't crack me one in the face. Luckily, I didn't bend the barrel, but I had to get a new stock from Hatsan USA. The gun was out of warranty when this happened, but they sent me a new stock for free. Awesome

I guess if it bent up it should bend down .
Should be plenty on barrel bending and home made benders .. matter of fact there's one thread on it this week.
Just puttin it out there ya know

Clamp the barrel flat to a bench/table and give a good push down on the buttstock. I have bought 2 bent model 34 Dianas. They tend to bend right at the breach block and bend back quite easily. Easy to the point that a wonder if they are a little weak there after the initial bend.
