Under $300 would get you a mueller 8-32 target scope with fine x hairs and mil dot plus target turrets and AO,not sure on the mueller quality there hit and miss.Vortex crossfire ii 6-24x50 v plex,BDC reticle puts it over $400.I have the Vortex with BDC on my long range Savage TR ,tracks extremely well and I can just make out my bullet holes at 200yds.I also have a sightron big sky 6-24 and the bullet holes are much easier too see at 200yds but at twice the price of a crossfire.I just bought a CZ455 off the EE and am looking to scope it as well,I would love to try the mueller but I bought a mueller APT in the spring and it was junk out of the box.Red field revenge 6x18 also in your price range.They will all be made in China or the Phillipines at that price point.Theres not much on the EE as I have been looking as well,most guys want close to retail for a used scope.
