Anyway to make a scope shoot higher?

[hometheaterman]

Ok first off I know this is a cheap scope but it's also on a .177 pellet gun so I didn't want to spend a ton. I previously had a 4x15 Tasco. One of the tiny ones. It worked but for some reason shot to the side and wouldn't adjust. So I finally went to see what Wal-Mart had. They had another 4x15 but they also had a 3x9x32mm Daisy Air gun scope for $28. I ended up buying that as I like the 3x9 a lot better. This gun is pretty accurate at least to me for a pellet gun. You can shoot pretty good groups of course you aren't far off either.

Anyway, I mounted the scope up tonight shot from around 4 yards or so. Maybe 3-4. I would liked to have gone further but couldn't due to the fact that It was dark so I shot it in the basement. It shot low at first so I turned the adjustment up. Still low so I turned it up some more. Once I got it about all the way to the up part it wouldn't turn any further up. I shot it and it hit dead on in the bullseye. I mean perfect.

However, since I'm at the end of the adjustment upwards at 4 yards or so am I wrong thinking that it's going to drop and shoot way low at 20 yards which is about what I want it sighted in for? I tried moving the scope forwards and backwards and it still didn't seem to adjust the poi.

What can I do to make it shoot higher? Is it going to drop like I'm thinking at 20 yards?

My other thing is would I be better off with a rifle scope? I was considering a Tasco 3x9x50mm with some .22 rings but I'm not sure if any other than the see thru's would be high enough. I think that scope would be nicer as if I ever needed to put it on a rifle as a spare I could do it versus I'm not sure this Daisy one is good enough for anything more than maybe a .22. Would I be better with that and see thru rings or to try to make this setup work? With the Tasco and see thru rings it was $46 vs the $28 I paid now so I really don't want to pay that extra as like I said it's a pellet gun. I wouldn't want something cheap like this on my rifle but I refuse to pay a ton for a scope on a pellet gun with pretty much no recoil. I just want this thing to target shoot at maybe 20 yards or so.

Make a shim out of a soda can. Cut a strip to fit under the back ring & add 1 strip/shim @ a time until your scope adjustment is back to the middle of it's setting.

definitely not better off with a rifle scope, I have heard of several high end rifle scopes being ruined by an air gun.... as for the adjustments, I would wait until you take some longer shots, as of now you cannot know what the overall ark of the BB will be.. with the adjustment all the way up, you may actually shoot high at 20 yards as the BB may still be on its way up.... do some more shooting, if I sited in my .22 at 5 yards, it would be WAY off at 10, 15 and 20.

4 yards is just not enough distance for the BB and cross hairs to meet up, think of it in terms of a laser coming through the end of the barrel, the cross hairs have to come down a long way to meet the BB. it would actually be better to get the scope closer to the bore than to raise it...

 

[hometheaterman]

So how far of a distance does a bb keep going up before it starts dropping?

As for a rifle scope how would you ruin one on a bb/air gun? I'm not saying it doesn't happen just wondering how?

 

[PT1911]

I am not sure of the specifics of how it damages the rifle scopes, but in essence, a rifle's recoil is straight back whereas a BB gun recoils back then forward... the forward recoil can damages scopes made for rifles... or at least, that is how I understand it...

as far as how high they go at the peak of their ark, I am not sure, but it takes more than 12 feet to reach that peak.

 

[hometheaterman]

Ok, thanks. If I can get it to shoot decently at 20 yards or so but it's still has the adjustment all the way up is that okay?

I don't get the shims. Are you saying put them under the rings or put them in between the bottom of the ring and the scope?

The bb gun hardly recoils at all that's why I didn't suspect it would ruin a scope but I guess maybe it can.

 

[PT1911]

I havent personally had it happen, just heard about it on more than a couple occasions... I would avoid the shims, if you adjust it all the way up and it is still too low, raising the scope will not fix the problem only create a new one... optimally, you want a scope to be as close to the bore as possible, that way the distance between the cross hairs and the inside of the barrel is minimized and the adjustments have less to overcome...

imagine a straight line coming from the barrel of your gun and a line slanted downward from the scope, where the two intersect is your scopes "dead on" point... this is what you adjust when you change the settings and ranges... the more parallel those lines, the better the gun will shoot... this is true of all guns..

 

[hometheaterman]

Ok thanks. I will try this thing out further away and see what happens. It says it's for the recoil of break open guns then it goes on to say or airguns or firearms and it's made by Daisy for air guns so I'm assuming it's fine on a pellet air gun. It's not a break open it's one you pump it up 10-15 times to shoot but I'm hoping it will work. The scope surprised me how clear it was for $28.

 

[PT1911]

that scope should work just fine...havent shot a BB gun in quite a while.. miss watching the projectile hit the target...lol

I had one of those scopes on my .22 a while back. It's a pretty good scope for the money. Only thing I didn't like 'bout it was that the reticle is a bit thick and I wanted something finer. It currently sits on a shelf for something else.

 

[hometheaterman]

I like the thick reticles although they get thin in the middle. For some reason I just have gotten used to the thick ones and like them better.

As for the bb gun yeah I hadn't shot one in a bit but decided to use it more as it's super cheap to shoot and fun too. The .22 isn't soo expensive to shoot but most everything else is and this is way cheaper than the .22 too and still fun.

 

[sharkhunter2018]

I like the thick reticles although they get thin in the middle.

I was referring to where the hairs meet in the middle. I seem to prefer a finer reticle as far as that. I like that style reticle, but it just wasn't fine enough in the middle.

I wish my air gun wasn't broken. Was my rabbit slayer when it worked.

 

[hometheaterman]

Oh ok I get what you are saying now. This thing is just something I can shoot in the back yard for fun since it's cheap and fun to shoot. I figure for $28 I can't complain about the scope as long as it works and honestly I'm not going to spend $100+ on a scope for a air gun.

So far as long as it works well when I step out to 20 yards or so I really like it.

Anyone tried this scope on a .22? Think it would hold up?

Held up for me, since thats what I had it on. Always held its zero. The only problem I had were the rings which slid forward after any period of extended shooting. I got tired of it and ended up drilling out the rings and just bolting them down. Looked like hell, but it worked. I blame the rings sliding on the fact that the receiver is aluminum.

You know, now that I think about it...I think part of your problem may be the scope rings. I still have one of the rings laying around, and they really are higher than they need to be. You might want to swap out the rings for something a bit lower. Like PT1911 mentioned with the scope being as close to the bore as possible.

 

[Suicide*Ride]

Use the "shim" between the scope & ring. Lay it (shim) under the scope on the lower ring half (back ring only) before clamping the scope back on the rifle. Once you get your "up/down" adj. back to the middle setting, lock every thing down. Works for shotguns & high powered rifles, so should work fine on your BB rifle. Good luck! PS. - You should only need 1 or 2 shims.

PT1911 said - I would avoid the shims, if you adjust it all the way up and it is still too low, raising the scope will not fix the problem only create a new one...

I read in the OP's post that -

Once I got it about all the way to the up part it wouldn't turn any further up. I shot it and it hit dead on in the bullseye. I mean perfect.

I figure by adding a shim (or 2) = .003 to .006, thus raising the rear of the scope, would get the OP closer to POI, & get his up/down setting back to the center of +/-.

PT1911 said - optimally, you want a scope to be as close to the bore as possible, that way the distance between the cross hairs and the inside of the barrel is minimized and the adjustments have less to overcome...

I've used the "See-thru" rings for years (for use when a shooter wants to use both scope and iron sights), on everything from a .22 rimfire up to .444Marlin, & don't quite understand your comment....

The greater the distance away from the distance you zeroed your scope at, the further apart the POA and POI will be proportional to the distance between the center of the scope reticle and the bore.

For instance, and these numbers are not mathematically derived, let's say you have a scope mounted with the reticle 2 inches above bore center. You are zeroed at 100 yards. If you move out to 200 yards, your POI and POA may change by 1 inch, let's say.

If you raise the scope up to 3 inches above bore center, zero at 100 yards, now at 200 yards your POI and POA may change by 2 inches.

To sum it up, the greater the distance between the scope and the bore center, the greater effect distance will have on POI and POA.
