i have a RWS diana 350 magnum and out of no were today it started shooting 6-7 inches high every shot, so i turned down the scope elevation as far as it would go and nothing. so i took the scope off and tried iron sights, still shooting high, so i turned the iron sights down all the way, still shooting 4-5 inches high every shot. any ideas?

Good question! Other than a bent barrel I'm clueless. Might be a issue with that rear sight.

Only thing i can think of is maybe your stock screws are loose. That is a powerful springer and the screws will come loose over time. If that is the problem you should loctite the screws.

Make sure the barrel is locking up tight and check the breech seal for any blow by...Also needvto check over a chrono, is it still shooting at same velocity??? Could be lots of things....

Good suggestions already, check for loose stock screws, loose pivot bolt, missing breech seal. Could someone else have handled it without your knowledge and let the barrel snap shut while trying to cock it? That will bend the barrel up. Look for a crack in the stock that might be allowing it to flex during the shot cycle.
It's a heavy recoiling rifle....if your velocity is down for any reason, such as blown breech or piston seal, the pellet will exit later than normal during the recoil cycle when the barrel is rising, raising your POA & POI.
Swab the bore and look for lead flakes or gunk near the muzzle and crown.
Good luck

Good advice! I don't think it's a breech seal issue. Chronograph readings are a must to start off with.

are the stock screws the ones on both sides of the gun near the front of the stock, if so they were loose. have not shot it yet going to do that now but i will see bc they were loose.

Take a straight edge and see if your barrel is running square on the topside and bottom of the barrel. Also check if the barrel is running parallel with the breech block. That's the rectangular block that has your caliber stamped on the side.

I'm leaning on a bent barrel so far. Do others in your household have access to your rifle?

If barrel is strait then excessively loose forearm screws could be the issue. The action is jumping in the stock upward when you fire it.

Well ! If your barrel isn't bent then others aren't to blame. Ireally sounds like loose forearm screws. The "Magnum" class break barrel airguns are prone to this. The M350 even more so !
