Taipan Veteran .22 Short /20 MOA rail/ short range shot trajectory problem

[tgif123]

I own a Taipan veteran .22 short (20 MOA rail)/ UTG 3-9x32 AO Compact CQB Bug Buster Scope/ Medium UTG Scope rings. I use it only within 30 yards max for pest control in my backyard. My issue that is that there is a big shot trajectory curve at close distances (0 - 30 yards) compared to my Benjamin marauder pistol so that I need to do a lot of calculations to hit targets even at such a close range. I don’t have this problem with my Benjamin Marauder pistol. I can just shoot and aim with my marauder .22/red dot scope and the trajectory is very flat at that same range. Both are sighted in at 10 yards. 

Other variables:

• Sighted in at 10 yards
• Medium Rings
• .22 caliber

Did I just pick the wrong gun to use at close range or can I fix this with height adjustable scope mounts like this one to adjust the angle from 20 MOA to 0 MOA? (Like this - FX No Limit Scope Mount, 30mm Weaver/Picatinny)?

Or any other suggestions? I’m pretty new to any type of shooting and would appreciate any suggestions! Thanks

(attached pictures for reference of the shot trajectory at close ranges)

(@25 yards the shot is 4 inches off from where I aimed)

What does it do when you zero at 20 yards?

Adjustable mounts should help but that totally defeats the purpose of the 20moa built into Veteran scope rail to shoot at long distances.

I would just zero at 20 yards and back the power down.

It should flat at 30 yards. It sounds like you don't have enough air. Does it do this on a full tank of air?

Thanks I appreciate the help. The thing is I am only using it in my backyard within 30 yards so I don't need to shoot at long distance. The shot trajectory stays on that same path as in the picture all the way out to that distance (30 yards) and I haven't tested further. I have tested adjusting the power output and pellets but I'm pretty sure the problem I'm having is with the 20 MOA rail. I just wanted to check if these height adjustable scope mounts will cause more problems or if there are any better solutions out there before I spend more money on something I might not need. I've already spent way to much on different scope mounts that are in my junk pile

What is the orientation of the target pictured? With a 10 yard zero, assuming an 18 grain pellet at 880 fps, you should be really high at 25 and 30 yards. A 10 yard zero is really not practical. Zero at 20, it will hit a little low at closer range, but will be relatively flat out to 35 or so. I don't shoot much beyond 50 yards, and I find a 20-22 yard zero about perfect in most rifles.

Thanks a lot! Sorry I fixed the uploaded picture to be the correct orientation. In that picture the shot is off by 4 inches @ 25 yards (I was aiming at the red dot below). I will try doing what you said and zero at 20-22 yards before I mess with the adjustable scope mounts

Like others stated I'd try a 20yd zero. On your prod the power is likely closer to half of what the taipan is which doesn't help either. But yes the 20moa will have some affect but really shouldn't change much. Your just shooting 2" higher at 10yds essentially than you would if you'd have a zero MOA rail.

 

[ctshooter]

I would say to zero at 20-25 yards. That's usually the range for a single zero setting. (ie: Different from two zeros when you sight in shorter - pellet going up and coming down).

Sighting in at 10 yards puts way too much angle on the shot, so even pushing it out to 13 yards would help a lot. I, for example, sight in at 13 yards for my indoor shooting and outdoors is almost spot on for 40-45 yards if I'm shooting in 700 fps range and scope is mounted ~2.5" from barrel. For anything in between I know I'll be holding under around and inch or two. 

Have you loaded all you details into ChairGun to find your best trajectory? If not I recommend you give it a try - that will also let you print a range card so you'll know the holdover/under or number of clicks for each range.

Thanks a lot! I will do that. I think your exactly right.

Thanks a lot! I will try changing the zero like everyone is saying. I haven't tried ChairGun yet but I will try that out too. I'm glad I asked on here before I swapped out the rings for the 10th time hah. Sometimes it's better to stop and ask for help.

As has been well stated, the 20 MOA rail is designed to use less scope elevation for longer range shooting. Shooting such at close ranges will be more difficult. Having the scope mounted as low as possible will help as will moving the zero distance out but that does defeat your need for short range shooting to a degree. 

 

[jarmstrong]

what is velocity the for each, prod and the vet and are you using the same pellet? I ask because you compare the 2 guns sighting performance

I would experiment with slower speed and zero at 17-20 yd , half the fun is playing around and trying different settings to get to a happy place

Thanks! Yea the medium rings are the lowest that will fit with my scopes. Yea I was hoping to be able to just point and shoot without a holdover/holdunder at such a close range but I guess I can live with it. It sounds like moving the zero out to 20 yard will help too so I will give that a try.

I'm still curious if using the adjustable height scope mounts to reduce the 20 MOA rail angle would work out or not but it doesn't seem like people are doing that for close range shooting like in my case. I could just be overthinking this whole thing too

Thanks! I've been testing with .22 / 15.89 gr. JSB Hades in both. I adjusted the hammer spring on both of them to the max power settings. The marauder is shooting around 600 FPS (I think) and the Veteran was close to 900 FPS if I remember correctly. Yea I agree, it's fun to play around and tinker to get to the happy place. I felt like I hit the wall with my testing in a way though so I ended up here  I will try what you said! Appreciate it!

 

[ctshooter]

The Vet is one of the easiest guns to tune. Just back that hammer spring out a bit and drop the 15.9 pellets down to 700 fps. Your shot count will increase significantly, it will be much quieter to shoot and IMO a good speed for 30 yards and in. You'll get to practice a little holdover, some wind correction, etc. But you shoot those 15.9s in the 900s and you're going to get bored quick pushing lasers at the target.

I don't see adjustable rings helping the situation as you describe it. Shooting at such close range with a scoped gun will have it's inherent problems. I have a couple of scoped pistols with see through mounts. I use the open sights for close distance shots and use the scope for for a bit further out. This doesn't help your situation much but may highlight the difficulty with a scope for short range. Hope you get it working for you.

Assuming your scope height is similar to what my Veteran was with medium rings..about2.4”.. when you zero at such a close distance, it’s the same as if you were to zero for a really long distance..like 85 yards. 

If you take the advice above to zero at 20 yards that will put you really close to a good spot


If you sight in to be about 1” low at 10 yards, you will be within -0.3 at 15 yards and +0.3 at 33 yards and -0.3 again at 46 yards so your “hit window” of 0.6” covers roughly 30 yards

Thanks a lot guys! This is very useful information. I'm glad I found this forum! 

 

[MushroomPsyche]

Having the same platform gun (Taipan Veteran long), I entered your zero distance data in Strelok Pro and the chart it generated almost completely match your off shots at 5, 15, 20, and 25 yards. Obviously I'm just eyeballing the measurements from your photos but it looks close. I can't confirm your 30 yards hole because I have no idea what power your gun is shooting at.

Please note the chart is in meters. I know you use yards but I didn't really want to change the application settings just for this quick check. Focus your attention on the column "Elevation, cm".

 

[Blejda]

What you need is regular rifle so you can have your scope as close to barrel as possible.My hw110 is zeroed at 35 yards.And at ten yards i have to holdover just around 1/2".So you just hold dead on from 10 to 35y and you will hit your target.
