You really only appreciate a piece of glass when you compare it side by side to its peers. The glass clarity and field of view is outstanding. S&B even requests there optics be returned to them for maintenance, very few have issue.
I use 1-2moa steel spinners @100 & 200yd positional shooting practice.
Here's the NRL 22 league target pack

The Athlon Ares is a pretty good scope for the price. More magnification never hurts if your shooting paper. I personally only use more than 15x when shooting prone stages more than 500yds or from the bench.
Most likely you will want at least 20moa base. It really depends on how many "useable" MOA your optic has.
For example CCI Standard velocity needs around 26.5moa of elevaton @200yds and 50moa @300yds.
Lucky for me my .22lr trainer likes CCI SV and Wolf Match. I use mine to practice holdovers, wind calls, and positional shooting. 300yds is a challenge with the slightest breeze.
