Either Schmidt Bender, Swarovski or a Zeiss. It depends...I want a variable in the 4 - 16x range with parallax adj on the turret and a mil dot reticle but I would like to keep the objective diameter below 50mm.
Probably a SF 6-24X 4200 Bushnell for my Cooper Varminter. A couple places have lowered the price down to around 500 bucks - a bargain IMO. A 30mm tube would be nice, but think I can make do @ mostly under 400 yds.
