Beeman Scope sighting droop !! Beeman .25 Raider

My Beeman Raider .25 is new. I sighted in with irons at 150 ft and it was fine at full pressure and generally shot in 3 groups. I set up a new Hawke on the Weaver rings set-up. The target is now at 30 ft and gun shoots about 6" off, then on the last line of the Empty green zone, the gun shoots zero. I never had issues with red-dot or scopes with firearms if the ammo is good and consistent and maybe takes a few shots and done. Does anyone have this droop issue, or are they scoping well? I'm not seeing way to regulate pressure if this true. If if wrong, please tell me what is up with the PCP Raider. Thank you
 
The Beeman Raider has a dovetail scope rail on it. Did you add dovetail to weaver scope mounts ? The factory breech is plastic and the barrel is held in with a pin under the breech. I changed all 3 of mine to aluminum weaver side lever breeches. Much more secure for barrel and scopes.
wow sorry of course it's the Dovetail. It almost looks like it could off.its center. I re-set all the rings, backwards and changed the parts around, and no go. Then I tried the scope upside down. Same 6" left groupings.
So It was thinking maybe rail dovetail was off, and this ring set is not my favorite with the simple clamp style. I think you did is what I was expecting. Did that get a decent group with scope? Do you have a source. Thank you
 
I installed BARRA 1100Z breeches to my RAIDERS. They do not sell the complete breeches anymore. I had to get a .22 breech for my .25 and put a tube on the probe and sand down to fit in .25 barrel. Very easy to do. I am a tinkerer and did not like the heavy hammer bounce so I made some 48 gram hammers to install- originals are 82-83 grams. I am waiting on lighter valve springs so I can reassemble and start to tune. Have had too many other projects going and these have sat for awhile. I do have 2 breeches .22 and .177 for sale if interested.
