I would like to hear from anyone who has had this scope and experienced a failure in it. Im currently shooting a rifle with this scope and i cant figure out my problem. If you’ve had one of these, please tell me what you experienced in the failure.
 
I have had one on my 20 ga shotgun for about 150 shoulder stinging slugs. No failure yet. But I have had scopes that needed occasional readjustments that can only be explained by the scope zero wandering. I have also dealt with scopes that just didn't work well. It would be easier to help if you explain your failure as there are other links in the chain that could cause innacuracy. As in loose bolts/screws, cracked/uneven rings, or even shooting a load that will never be accurate. Always start with checking your entire mounting system. Then try another load in the rifle if you haven't. Depending on twist rates you may need to try different bullet weights. If no improvement you need to try a scope that has been proven. You can even borrow a friends scope if needed. If everything checks out with those steps and you verify that that pst is a pos send it back to Vortex.

What exactly is the problem you're experiencing?

I wish i had a better answer for that. Long story short, ammo has not changed. Rifle did not change, just the scope. Sight in went very well, and i was confident. First hunt, missed twice @250yds(chip shot). Back to the range after, cant hit paper. No drops, knocks or anything to bump it. It was mounted the way it should have been. I sent it to vortex, and they claim nothing wrong with it. The rifle shot groups with same ammo and different scope afterwards.
 
Did you remount and try again? What kind of rifle? I just went through this with a friend. He has a Remington 700 ADL in .223 that's a extremely accurate. Put a new scope on it and groups opened up. He took it all apart and reassembled, re-torqued, voila, it's grouping again. The internal mag box wasn't in the action correctly and causing pressure.
 
I fell hard and my Tikka CTR rifle went tumbling end over end down a very steep hillside. Probably at around 50yds it finally came to rest. The muzzle brake was packed full of dirt as was various other areas throughout the rifle. I thought it was destroyed for sure. After getting back down to the bottom I got it halfway cleaned up enough to put a few rounds through it at 100yds. To my surprise it held zero perfectly, no changes at all. This was years ago and still haven't had any issues with that scope and rifle. With all the bad talk out there about the vortex scopes, I suppose I got a "good" one. 🤷🏻‍♂️
 
I've had a few of the PST 2's over the years (still have two of them). Can't help with failures since I haven't experienced it. The one on my 22-250AI rides around in a side by side quite a bit. Another lived on my 338 RUM and it's still kicking.
