When I upgraded from my budget spotting scope, I went to a mid-low range spotting scope from Konus (20-60x100).

It has done pretty well for me and based on what I had before it was light years ahead. After several years it leaves me wanting more. On a still day I can easily see7mm-.30cal holes at 300yds in plain black background targets. .22 cal maybe depending on light. It has stability problems in wind because of its sheer size (100mm!) and weight. It bounces at high magnification enough that I have to rest my hand on it when gusty. I use a SLIK camera tripod typically, but I am going to upgrade to a Creedmore sports or the like. People at the range use it to see what they need that whatever they are using can't. I don't usually pay attention to what they are using though. It will fog heavily in bad weather too, but I'm rarely at the range then anyway.
Whatever you get, make sure it has an angled eyepiece. Then you can have it next to you on the bench and lower when standing. If mine was straight I would have to bend down to look through it as my tripod won't extend enough. I wish I would have spent more money for nicer glass but it works for me for now.
Good luck with your shopping!
