The scopes on that video are worth considering. They are not expensive, and all you need for any rimfire application.
No doubt a Bushnell 6500 would be "ultimate"... overkill. It is a super nice tactical scope for long range shooting.
Are you going to shoot at known distances to the targets? Then get a scope with a fine reticle, parallax adjustment, and external turrets you can dial in the range. Those Bushnell AR and Rimfire scopes with side parallax adjustment, and swappable turrets for .22 LR and .17 HMR will do all you need. Simmons is almost identical, just less tactical looking. So will the Nikon Prostaff Target AO with fine crosshair and small dot.
If you are going to hunt with it, something with BDC hashes is worth a look, like the Bushnell AR series, the Bushnell Rimfire 3.5-10x36 AO with swappable turrets, the Nikon Rimfire scopes with exposed turrets which match their AR-15 and .308 scopes, and the Vortex Crossfire Rimfire. I use a Hawke 2-7x32AO Mil Dot on an AR-22. Another line of scopes you might look at are the Mueller APV or Sport Dot. I have a Mueller 3-9x40 Sport Dot which I took on a trade, made in Japan, and surprising clarity, 1 MOA red dot, and 1/8 MOA turrets.
I have been using a 6x42mm on a rimfire for 15 years, matching the same scope on a .308. I am going to replace it with the Primary Arms 6x32mm with the ACSS reticle. Go look at the detailed through-the-lense video of this scope ranging and shooting targets beyond 200 yards.
