unless your shooting beyond 400yrds a 3x9 will work in eastern oregon.everyone assumes its all long shots here and thats just not true.i used a bushnell 3x9 chiefscope for years until the wife bought me a vortex diamondback.the vortex is a good 4x12 and i like the reticle.bushnell dont have a good warrenty so you might look around,i got my 4x12 for 220.00 and am happy with it.they also have a very good lifetime warrenty.
