You picked some items on the cheaper end of the scale, increasing dramatically potential issues.
On alot of cheaper actions they are not strait. So when you torque down the rail you are actually bending it out of plane, and will bend the scope causing binding and other issues.. You can shim and then marine tex to fill the gap and get it strait.
Its something that needs to be checked and fixed on ANY bolt gun if you want it to work correctly.
Its possible you have a bad scope, bad rings, bad action, bad ammo, incorrect installation ect. There are alot of variables and its hard to eliminate them without replacing or doing in depth diagnostics.
I am not trying to preach or be a smart ass, but this is why many of us spend more money on quality gear. It all but eliminates these issues or at the very least, makes them easy to identify and then eliminate.
Lifes short and we want to have fun shooting or hunting with gear we can trust. Nothing worse than having to chase demons with the limited time many of us have to do the things we love.
