Fx impact fac mk3

[bigboodydaddy]

I have just purchased a fx impact mk 3 in fac and topped it with a ATN xsight 4K pro 5x20 day night vision scope with a 1500 abl attached to it I’m having trouble getting this to work properly zeroed at 50 yards with jsb 18.13 pellets Bullet on Bullet at 50 yards but when getting further away from the target it’s a mile off as is when getting closer to the target has anyone got or using the same setup as myself shed any light on this matter I’ve put in the correct info into the scope and ballistic calculator is on. Thanks in advance

The Impact is not an "out of the box and shoot gun". It needs to be tuned to the weight and type of pellet you are using to achieve maximum accuracy. You need to make sure that the muzzle velocity is less than 950 fps for pellets because they tend to become unstable at transonic speeds. You could also try using slugs instead of pellets for better BC, although once again the gun will need tuning depending on the weight of the slug. A friend I shoot with has one and also tunes them for a RFD. I'll see if I can get you some info.

I dont think its the rifle I cant get the atn xsight pro 5x20 to work correctly with the information i have entered into the scope for the ballistic calculator to calculate the point of impact for me been trying for three weeks now ??? Thanks for the reply though.

Post another thread with a title like "ATN X Sight Pro 5 X 20 Problems" You should get some answers.
If you think it's that and not the Impact, the easy way to find out is to put a known day scope on and test again.
