    Well, I had some time to do another plinking session with this Venom. I decided to challenge myself and only shoot at the quarter size spinner at 20 yards. I kept missing a tad high and right or left. I tinkered with the scope but no luck. The only difference from the day before was the rifle was in the AC and cold the prior day, and yesterday I had left it in a warm room to prevent it from condensating like it did the day before.  I was also quite exhausted yesterday from moving heavy furniture in the heat, and was terribly overheated. I may have been a tad shaky.

    Its time for another paper session and maybe a new Hammers scope.

    Switched to JSB Diablo Exact Jumbo 15.89Gr and it loves them. 5 bullseyes in a row at 20 yards.

    I got to spend some time today with splatter targets. I was able to get the Venom to do very well with both the JSB Diablo 15.89 and the Crosman Premier Hollow Points 14.3Gr…..I will post pics of the shot cards later.

    I am glad to hear it is behaving for you. When you can get some Predator Polymags to try too. Mine love them along with the two you already mentioned. I picked up a Crosman Phantom (basically the same gun, only different) because I wanted a gun with sights on it and it has them same tastes as my NVD. Must be a Crosman thing.

    Hey idk if this got resolved but i just wanted to suggest trying a straight shooters sampler pack to find the best pellet for your gun.http://www.straightshooters.com/straight-shooters-full-pellet-sampler-.22.html
    I used the .177 pack to find the best pellet for my gun. It helps. Just print out a bunch of paper targets to keep all your tests consistent.

    I posted my test, /topic/finding-the-right-pellet/

    Crosman Premier Hollow Points at 20 yards. The lower yellow shots were the first few and I dialed the scope up almost a 1/4 turn during this session.

    Here is a card of JSB Diablo Jumbo 15.89Gr I ended up dialing the scope up a tad thru this session due to the lower 3-4 shots. The top right yellow shot was my fault, I flinched.

Thanks Wolverick, I updated the thread with shot card photos.

    OK, so after spending a couple of hours dialing in this 22 with shot cards I had it performing very acceptably as pictured above. Yesterday I shot 7 shots in a row at 20 yards all at a quarter size spinner. 7 perfect shots, then I proceeded to miss every shot with it since then……..I think the scope is at full UP on adjustment and isnt holding the lens properly or something???? I say this because while I was dialing the scope up on the shot cards if I went beyond a certain click on the Elevation it would go all wacky but if I dialed it down a tad and just aimed slightly high it was great….

    I feel like it has something to do with the internals on the scope, as the mounts are loctited and torqued and its not moved at all. I know the Centerpoint 4×32 is junk…..but dang its really really junky….. Any insight provided is greatly appreciated.

    I have considered a Hammers AO scope or Magpul Flip Up weaver rail open sights. Its really frustrating to have a rifle perfect then the scope goes wacky.

    Bobbed I haven’t had very good luck with center point either . But my Buddy AJshoots told me he has had Great luck with the little BSA scopes . He has a gun that is a certified scope killer and he said he hasn’t ever had one fail .
    Look him up in here and PM him and ask which model it was he uses . He’s a good dude and Very knowledgeable.

    My NVD has killed three scopes so far including an UTG which was airgun rated. It currently has whatever Hatsan sends with their Edge Vortex. It is cloudy but has stood up to the NVD thus far. The break barrels are all hard on scope weather springers or pistons. That is why I have since stuck to guns with open sights, I just can`t afford buying new scopes every month.

    ​I have a holographic sight (red dot) coming for my Phantom because the sights on that are just junk. I have it on good authority they hold up very well to piston guns.

    Bobbed–You’re describing EXACTLY what happens when you have a drooping barrel. Don’t panic, it’s easy to fix. The included Centerpoint scope may not be very good but if you have a drooping barrel (a LOT of break barrel rifles do) you’ll still have the same problem with a new scope. Watch this and learn how to fix it!

That is exactly what seems to be occurring. i watched the video. Then I started looking closely at my scope and mounts. The scope has slid about an 1/8 of an inch rearward during the last 500 shots or so. It was very minimal but something to be noted. The clamps at the weaver rail are still locked in the exact position I built the rifle in.

    I did however decide to take notes on where the elevation and windage adjustments were. They most certainly were to the outer limits of their respective adjustments. Both adjuster knobs were at 3 1/2 full turns out from fully seated. So they were UP 3 1/2 turns and RIGHT 3 1/2 turns.

    I will try and shim the rear mount up a tad and try and dial in the scope settings and keep them under 2 full turns out from seated. The Center Point scope SAYS I can adjust the focus by turning the focus adjustment ring?? The entire eye piece will turn and then there is a locking collar at the front side of it. I turned it both all the way in and all the way out. It doesnt seem to do much at all. If i turn it all the way out it seems to make the cross hairs blurry. So I tightened it back down until I got nice crisp cross hairs and locked it down.

    Looks like I better get to work and shim this scope and see if the problems go away. Thanks for the knowledge. I am a newbie still and have lots to learn. I will report back.

    Some days u just have to walk away from things……

    So……after discovering the scope had slid in the mounts, I removed the scope and the weaver rail clamps for the scope were loose as well. Turns out the bolts felt tight because I loctited them but when the scope was removed from the cradle they moved freely although they hadnt moved fore or aft….The clamps had this scope protectant tape in them and it had gummed up and was allowing the scope to move. So i removed that and cleaned out the residue. I figured I would assemble everything without a shim to see how things were working as the far RIGHT adjustment had me concerned a bit. When I tightened down the mounts on the weaver rail I noticed the mounted pulled the scope to the right….So I decided to flip them so I may keep the windage within range. Mounted it all up and set out a 10 inch splatter target at 20 yards. Didnt even get close to the paper…..LOL

    Its too darn hot for this today. It really has me miffed that I spent all that time dialing it in, and trying different pellets only to have 2 good days with it. I guess I need to flip the mounts back to the direction they were before. Then shim the rear mount up a tad and hope me tinkering with that eye piece setting hasnt thrown a huge variable in the mix.

    Do I need that tape inside the clamps?

    That front “eye piece” ring is to adjust the clarity of the scope’s RETICLE to YOUR eyesight, nothing more, nothing else. Point the scope to something with an unobstructed view. Like the sky or towards a light in your house. Adjust the clarity of the reticle (the crosshairs) to their sharpest. There, now it’s adjusted for your vision and you’re done. No need to touch it again unless it gets turned by accident or for another shooter’s vision. Re. shimming the rear mount–it doesn’t take much. Often the thickness of a business card or the aluminum cut from a coke (beer if you like,lol) can will be enough. Cut pieces about 1″ square.
    Hope this helps. Hang in there, you’ll get that sucker shooting straight!

    OK, thats what I did. When i had the scope off I spun that eye piece until the cross hairs were clear. its locked down now. One thing to note, when I loosened that eye piece the entire eye piece had slop in it allowing the crosshairs to move with the eye piece. When I tightened the lock ring against the eye piece it no longer had that slop.

    I hear ya re. how frustrating it can be trying to figure out where the pellet’s hitting when sighting in. Especially after having to shim to get enough vertical adjustment. Been there, done that lotsa times. Don’t try to find that pellet strike on a normal target. Draw a circle a couple inches in diameter with a magic marker on something BIG like a paper grocery bag and if need be you can start close, say 10-15′ or so. That’ll allow you find out where it’s hitting and then you can start twirling those adjustment dials.
    You’re right about walking away sometimes. Something that’s hard for me to do but good advice. I’m in Michigan and like you it’s too darned hot & humid to spend much time getting frustrated today. Drink one of those beers and tackle it in the morning when it’s cooler!

    I just couldnt let it be…A storm started to roll in and brought some shade and cool air. I took the opportunity to remove the scope again, remount the mount bases. Then I used 3 strips of Gorilla tape in the lower rear mount, and one strip each in all the rest of the mounts.

    I shot at a leaf in a pile of wood chips at 10 yards and dialed in until I hit the leaf. Then I set my splatter target out at 20 yards and started to dial it in. My elevation is now about 1 1/4 turns out from full tight and my windage somehow managed to be around 2 1/4 turns from full seated. Much more acceptable than the 3 1/2 turns out they both were previously. Although this card looks terrible due to me dialing in the scope it still shows some nice groupings. the small groups directly above and below the bullseye were at the end of my adjustments. Once I got the bullseye a couple of times I called it good enough. The sun came back out and it was too hot to be outside anymore.

    I will keep a better eye on the mounting screws from now on, and I appreciate the input from everybody. Thank You all very much
