Like MT said I loved the Mueller when I had my PCP. Too bad they really aren't meant for springers. Are you shooting PCP or Piston class? Open, Hunter, or WFTF?
I'm going to buy a Mueller 8-32x44 Side Focus.It's an exceptional scope for 250 bucks. Do a search......you won't find a bad review of it. There is a member here, SciGuy, that started a thread on it in the Optics forum.It does not have a mil-dot reticle......and it will not work on a springer.It has 1/8 MOA adjustment.For PCP open, though, it should be a very good quality scope for the money.Mike
Don't skimp if you are going for Worlds. A used B&L Elite would be a good starting point, either 6-24 or 8-32. ...... For the BL look used as it appears the new ones won't focus to 10 yards.
