A few questions about my new Burris Fullfield

So I got my Burris Fullfield II 4.5-14x42 mounted today and attempted to sight it in. I noticed a few weird things right off of the bat. The first ones is the paralax adjustments don't seem anywhere close. However, I know this sometimes happens and it even says in the manual they might be off. I found that with it set on 100 yards the picture was very blurry at 100 yards. If I set it between 50-100 so around where I'd guess 75 is, it seemed to work great at 100. I made a mark here and I guess this is normal.

The next issue and this is the biggest imo. It seems like if I put up or down pressure on the eyepiece it seems like it moves just slightly. It looks like the cross hairs are jumping up and down by doing this even with the rifle 100% still. I'm guessing the cross hairs aren't moving, but the glass in the eye piece making it seem as if the cross hairs are. Now, I've noticed in all of my other scopes if I loosen the eye piece to adjust focus they do this too. However, once I tighten the lock ring down on most of them, it doesn't do it anymore and the eye piece is 100% tight. Since this scope isn't designed like that it doesn't have a lock ring to lock the eye piece down since it's always turning. Anyone else experienced this? Is it going to cause me problems shooting? Should the eye piece be 100% wobble free, or should you be able to move it slightly like this by pushing up and down on it? If any of you guys have this scope could you please let me know?

The other question I have which isn't really particular to this scope is if I adjust the AO will it hit the same poi? Like say I have it sighted in at 100 yards with the ao set on 100 yards. Then I adjust the ao to infinity, or 400 yards, but still shoot at 100 yards, will it shoot to the same spot, or somewhere different?

I tried to sight it in and I'd put 2-3 in the bullseye, then 2 or 3 about 1" high and 1" right. This repeated itself over and over, so I'm not sure if it was something with the scope, or if it was just me not shooting well today.
Thanks guys.
 
I've had several Leupolds, and have been less than impressed with all of them. 3 out of the 5 have had to go in for repair. Then I have a Burris Fullfield II 3-9 that I love. It blows away the glass in the similar priced VX-I from Leupold, and I even found it better than the VX-II I had. I'm just not sure about this Burris. I wish I knew if other FFII's did that eye piece wiggle. I'd check my 3-9, but I don't have it here with me.

I do have a Leupold sitting on the shelf here unmounted that is my favorite one out of the 5 I've had, but I really want more power than it offers.

If anyone has a Fullfield II in any size if you could check if the eye piece has a slight wiggle and report back I'd greatly appreciate it.
 
I should also mention that the eyepiece doesn't feel loose. It's not an obvious wiggle, it's just enough that you can't really feel it, but can see it so it makes it look like the cross hairs are moving. You can also see it slightly if you look where the gap is right past the "magnification ring" part and it's barely moving. I just thought I'd mention this so no one thought it was super loose.
 
I have 2 words for you.
Ziess Conquest
A little dearer then what you have but IMHO hands down the best value glass you can buy period! A Leupold costing twice as much still won't compare to a Ziess Conquest.

Okay, I called Burris and they are supposed to be sending me a call tag for this scope so I can send it back and have them check it out.

I also want to add that I finally got a chance to check my other FFII 3-9x40 and I noticed this one does the exact same thing. It feels as if the eye piece is pretty tight, but it moves just enough to do this. It's hard to tell on that rifle if the eye piece affects the poi or not as the rifle it's mounted on shoots about 2" groups at 100 yards with ammo it likes. It does that consistently and has with more than just this scope. It doesn't have any problems shooting the same 2" groups the rifle normally will.

With this other 4.5-14x42 I tried it and it's really hard for me to tell if it's me or the rifle. It was shooting about 1.5"-2" groups and the rifle usually has no problem shooting sub moa groups. However, I've had days where 2" is the best I could shoot. I mounted the Nikon back on it and shot it a couple of days later and I shot the sub moa groups I'm used to, but it's really hard for me to tell if it's me or the scope.

I'm really curious to hear if guys that have this scope that shoots well for them could check this out and see if theirs does this. If you guys that have them can check them by locking the rifle down in a vise, or putting it on a bipod or something that holds it really still, then wiggling the eye piece while looking through it and see if it makes it appear the crosshairs are moving. If you guys could do this I'd really appreciate it. Thanks.
 
if I adjust the AO will it hit the same poi?

Not necessarily. That is a parralax adjustment. If you are aiming at a 400 yard target and the AO is set for 100 yards (as an example), you will have parallax issues.

If you have no parralax, the crosshairs will stay on target even if you move your face around. If you have parralax, as you move your eye/head around the crosshairs will move around on the target even if the rifle is being held perfectly still. This means you could put the crosshairs perfectly on target but the point of impact would be somewhere else.

For example, the last time I went to the range with my friend, we sighted in a 3-9x scope (with no AO) at 100 yards. We both had the same point of impact. When we stretched out to 400 yards, we had very different points of impact. He shoots left handed and had a different sight picture than me.

On a positive note, if you have the exact same sight picture every single time you shoulder your rifle you don't have to worry about parallax.. meaning you can adjust all you want and not have to worry about point of impact.

I pulled out my 4.5-14 and I couldn't duplicate what you are experiencing, that is if I understand your problem correctly. My experience with scopes that were broken/needed fixing is that they loose consistency all together. This would lead me to believe if your patterns were consistent, even though they weren't as tight as you would have liked, it's probably not the scope.

If it is the scope, I have no doubt Burris will take care of you. With my 700 ADL, federal gold medal match and my ffii, I've shot some pretty respectable groups. You bought a great scope and I'm sure you will love it once you get this figured out! :)
 
When trying to duplicate this, did you just push on the eye piece up and down a little while looking through it?

Yeah, I'm not sure if it's the scope or was me, and I'm a little less concerned about it seeing my other one does it too.
