Good afternoon guys,
I have a Benjamin NP Trail 1500 XL air rifle and its performance sucks to say the least.
About 3 weeks ago I went to an indoor shooting range which had a maximum range of 16m. I totally missed the target so I brought it closer to about 6m, zeroed my scope on the bull with 3 shots and moved it back to 16m. the bullets were flying all over the target, everywhere except for the bull. I ask the armsdealer to have a look at it and he ordered a replacement scope, Nikko Stirling Panamax, from the supplier. New scope did exactly the same. He took the scope off, unscrewed the scope rail and screwed it back on with little bit of locktite to ensure that the rail does not come loose. We put the scope back on and I took it to the outdoor shooting range yesterday, set up the target at 25m and tried to zero the scope. All the screws are tight on the rifle stock and I was using a Buffalo River bench rest to shoot from.
Because of the speed of the pellets, I shoot with the heavy copper plated H&N Barracuda Power 10.19gr. It used to shot a respectable grouping but now I have no confidence in the rifle accuracy.
Can I have some advice as to what to do plse? Should I replace o-rings, etc??
