It seems that on most of my guns, I'll have it sighted in at a certain distance with a certain pellet but the next time I take it out the POI will have shifted from 1/2" to 2" at 25 yards. Could this be a trait of cheap scopes? I have always economized when it comes to buying scopes. The most I have paid is about $125 with most about half that amount. I guess I've been afraid if I ever bought a really good, ie. expensive, scope I would be spoiled and would no longer be happy with my cheap scopes. If the POI shift is due to my cheap scopes, what would be a good scope for say under $200? Almost all my shooting is 50 yards and less.
POI Shift - gun or scope?

My yard is about the same.
What gun are you shooting and which projectiles?
UTG BugBuster on my HW35 meets all my needs. The only downside is me.
Always good scopes here in the classifieds.

Could be different reasons for each gun. Many cheap scope work well. Are you talking springers or pcp?

For my powder burners, the scope / mounts are the first thing I would suspect. On airguns, it has almost always been the complicated barrel / shroud combination that causes POI shifts for me. It has RARELY been the scope. My FX Impact was the worst of all my airguns. My lowly Notos still holds the top spot for holding POI, even when hauling it around in my car in a soft case.

Is it a 2nd focal plane scope and are you using the same magnification you zeroed with if so?

I'm just wingin' it here. If your guns have long barrels hanging out, unsupported along the entire length of the barrel, then it's a droopy barrel. It's more droopy as the temperature rises and less droopy when the temperature cools down. That's to be expected I think. Scopes are also affected by temperature -- good ones not as much, I guess. But I wouldn't jump on the "I need a new scope" bandwagon until determining if the POI shift due to temperature changes is perfectly normal.

I have used UTG BugBuster's on a couple of springers and found them quite adequate even out to 50 yrds and beyond.

I dunno why there isnt a sticky on shimming but airguns tend to need about 20moa more up. If you loosen your elevation screw all the way to achieve this then you relieved all the spring tension and your scope is going to get sloppy.

I hate the Notos because the rail is parallel and even if you buy the right adjustable rings on the first try it costs half as much as the gun. Cheaper better rifles exist where you dont need to dump $150 extra to add a scope and bipod.
