Fx Impact POI help

also as well did you ever hear of barrel indexing? not a lot of rifles offer it. but if you can get a rifle like rapid air weapons bm500 or a Thomas rifle you will have a rifle you can index.
just trying to help yo as it may not be the rail at all.

You try a group at say 20yards to see if point of impact moves to the left. . That would confirm it is an alignment issue. 

Can you bring it in to 15 yards and then stretch it out to 100 or even 125 yards? If you can get a calm day that will clearly show any left to right shift or zeroing issues.

Then, once you have it left-right centred at 125 yards, take it back and see if you are still dead-on at 50 yards. I recommend using a good lead sled like the DFT2 or something similar. 

If that doesn't work, change out your scope rings. I've had good scope rings with poor alignment in the past.

In my experience it is more likely a small problem then a barrel alignment problem.

check out network 54 on barrel indexing. I learned all about it and then bought a raw bm 500 as a result with an idexable barrel.
​problem sloved. was and is the best air gun buy accuracy wise i ever bought.

Rail's bubble levels may not be perfectly centered and if you don't check them with another bubble level on the gun itself it may produce cant errors rather than solve them.
And check for wind between the target and you, maybe there is no wind where you are but in the field it may be different

If it's one of those cases then yes, nothing to worry about. Have you got what i was saying about the bubble level not being correctly calibrated?

The wind is for me the most probable cause. Keep in mind that you have 70yds in front of you where the wind can behave different than where you are. But check cant just to make sure. Regards

I like to use a level that is attached to the scope tube because you set it to read level when the gun/scope IS level so the quality doesn't come into play so much. With a rail mounted level you have to rely on the guns rail being perfectly level AND hope the bubble level was made well enough to sit level.

I had this same problem and a scope level cured it for me... I would zero at 25 yards and my poi was always left at longer distances because I was unknowingly canting the gun by mistake. Very hard to not cant without an anti-cant device.

Sounds like you may be getting some pellet spiraling. What velocity are you shooting at?

Here's an example:

Hello Isaacrm1,
Once upon a time I had a similar problem when shooting from the bench, and that got worse when I shot standing offhand. Then one day I happened upon this video and it completely eliminated the problem for me. I am going to suggest a test for you to do that will either pinpoint the problem or eliminate this as a possibility...I want you to take three sheets of white paper and make a cross with black marker on them. Place the three targets at 70 yards...then from a bench rested position shoot 10 shots at each target while overlaying the black cross on the paper with the cross hair of your scope.

On target number one I want you to pull the trigger on each shot with the very tip of your finger, on target number two pull the trigger each time with the center of the pad on your finger, and on target number three put your finger on the trigger so that the crease of your finger is touching the trigger. The first one should hit to the left each time, the second should hit dead on, and the third one should hit to the right each time.

When you finish this test, do it all over again while only pulling the trigger with the center of the pad of your finger...but this time I want you to pay special attention to keep your rifle perfectly vertical so that your rifle and cross hair are level. Be positive that you are not canting the rifle at all. This test may surprise you also!

Watch these two videos by Kirsten Weiss and listen to her explanation, then do the tests I described above. You may be very surprised by the results! By the way, do not underestimate this gal...she is a professional and we are totally blessed that she shares her secrets with us. I wouldn't want to have to shoot against her for money my friend! 

I am adding this advice on trigger control from David Tubb who I personally believe is the greatest competition shooter of all time. I believe his records will stand for all time against all comers. One of the things he is adamant about is that you do not let your trigger finger touch any part of the rifle except the trigger! And the placement on the trigger has to be exact. Want to be a better shooter? Take a lesson from these two nice people and practice the right way and you will be amazed at the results. If I can do it you can too!

All the best, Chuck

disassemble the scope and rings and mount it again trying to tighten the screws partially.

Thanks for the links, and information. I've been trying to work on 100 yard groups with my Impact, and had never really considered how much the rifle cant angle can affect the shot. With the high mounted scope, and the amount of pellet drop at that that distance, it's probably worst case when it comes to cant angle. I think I'll take a level out to make sure I hang my targets as level as possible from now on, and I'll make a conscious effort to make the reticle line up with the lines on the target. I'll probably shoot a few groups with an intentional cant just to demonstrate the effect to myself. Should be fun, and maybe even useful.

Cheers,
Rusty

Rusty, do it other way round. cant the gun to get the POI where it should be then you look at it realisticly if it is the root case.

One thing you might check/consider.....if you are adjusting your scope to the max elevation or near that, an out of center mounting will cause the impact to move left or right, depending on which way it is off center. Doesn't much matter what kind of scope. Think of the adjustments as a circle. When you near the edge of the circle in any direction, a change in one adjustment will affect the other. The answer is to add more elevation by shimming your scope so the area you use is more centered and/or correcting the horizontal misalignment.
