Here's a rhetorical question: What are your getting in return for each dollar spent?
Answer: Durability. Repeatability. And above all: Optical quality (OQ).
One can expect very usable durability and tracking repeatability at any price point above $850-1000. And the reality is that, in good lighting conditions, only an experienced eye is going to notice an OQ difference between a $1500 scope and a $2500 scope.
I've participated in any number of side-be-side comparisons of scopes ranging from ~$1200 to over $4000. The high-end optics differentiate themselves in "bad light" - very dim or very high contrast, and at maximum magnification. In one comparison, multiple guys looked down a 550-yard range through a $4000 ZCO 5-27x56 and a $3000 gen-3 Vortex Razor 6-36x56. Everyone agreed: the ZCO was slightly better - but no one thought it was $1000 worth of better.

My most oft-cited example: At my favorite match venue, one of the lanes has round steel plates on a little berm in the shadow of a tree line about 800 yards out across an open, shallow "valley" (which mitigates mirage). Only the berm and targets are in the shade. By afternoon, dark gray plates against a dark brown berm in that high-contrast environment are really hard to see. With my old gen-2 Vortex Razor 4.5-27x56 scope, I could not see those plates - only the yellow paint stripe on the fire hose from which they were/are suspended. With my ZCO 5-27x56, I can see the plates fairly well. With one of my gen-3 Razors, I can make out the plate but not quite as well as with the ZCO.
And that's at centerfire ranges 300-1100 yards. The vast majority of rimfire PRS targets are inside 200 yards; the furthest I've ever shot in one of those competitions is 415 yards. You just don't need top optical quality at such short range. Certainly, it's nice to have. But is it necessary? No.

Here's another thing I learned from experience: a high-magnification scope with .2-mil reticle subtensions can bite you at short rimfire ranges. I shot a really fun match in Virginia where targets were spread in deep shaded woods 75ish yards out. I had to zoom out to 10x or so on my gen-3 Razor to find the targets quickly in the dark cluttered background. Even with illumination turned on, I could not differentiate the .2-mil marks. And I needed to.
After that, the ZCO 5-27x56, with its thicker reticle, came off my main centerfire rifle and went on the Vudoo. The 6-36x56 Razor is on the centerfire.
-------
So, my $.02 based on my own experience is that a $1500-2000ish optic with roughly 5-25x zoom range and a reticle you like is your best bet / return on investment. Higher magnification will almost never be useful in competition but is often useful for spotting hits on targets on range days - at the possible penalty of reticle subtensions being unreadable at low magnification.
Good luck.
