2 POI what gives?

[Healthservices]

 So ive been tuning my impact with the barrel tuner and I had this issue for a while. But i seem to constantly tend to have two groups when shooting groups. What gives? Am I holding too tight? Is it my heart beats? Is my retical moving about? Or am I just not having the same cheekweld everytime?

It's an FX special feature, no extra charge.

What pellet and what speed? Try turning speed down 10% and check again.

Check your scope and stock for tight fit.

Double the the nut at the end of the trigger....

Right now im just trying out some of zan's slugs 30 gr at 820. I think i still have it when i fire off the jsb 18 gr at about 820. I was hoping i could tune it out. (Probably still need a lot of tuning yet). I think it maybe the loose nut behind the trigger as i get all hype up when i get 2 or 3 slugs in one hole then the 4th and 5 are off to one side in another group.

I get this ALL them time with slugs. Your close to a tune is what Im seeing. This is why never stop at a 3 or even 5 shot group when tuning!

Thanks Eric, I try to get a ball park with the 5 in a group then go back with more shots in the better groups. Hopefully not wasting as much slugs but at the same time possibly missing out on some tuning.

I noticed the POI would move occasionally on my Avenger 25 as much as an inch at 100 feet. It shoots lots of little (`1/4 inch) groups so the movement is fairly obvious. I think the change is two things in my case. First, I needed to better focus the lens of the scope closest to me to minimize the poa shift when I move my head. I could move it an inch without touching the scope initially. But mostly I could shift the POA horizontally, not so much vertically. My POI change was mostly vertical. Then I noticed today that it shifted over half an inch based upon whether I held the fore end against the rest. Not holding it would cause the POI to go up. Probably wouldn't do it or do it as much on my little Prod since the fpe is less than half the Avenger.

So if you haven't carefully focussed your scope and/or you are non consistent on your hold, you might want to change.

Thanks jim I know I have issues with consistent cheek weld and hold. I try to keep an eye on it and strive to be consistent and aware of it each time.

2 different , but tight groups means you can rule out any problems with the gun. Has to be like you said the way you hold and position the gun. Another way to test it is to let a few other shooters shoot your gun and see what their results are.

Thats a good idea. I just need to have somebody with me to do that.

This was another thought. I dunno if it would even work, but in theory it should if things don't get knocked out of place. A camera like a gopro scope mount. Mounted with a cable hooked up to another lets say larger screen. Not attached to the gun. If the camera does not move position and is at the same spot all the time and i aim exactly at the same spot looking thru the larger screen and not the scope. The POA should be the same spot. This would pull me out of the equation. Right?

Wait i just remembered. Everything will be flipped because of the mirror . 

Doh!

Late but would like to comment. I've had that happen as well. Only with zan and avs slugs, the hybrids and nsa didn't. Tried silicone based lube with same results going to try slip2000 next. Did you get yours figured out?

It was me, my hold, and eye placement behind the scope giving me 2 point of aim and impacts I just did not realize that I was doing it.
