I have a TC Omega Z5 and a Traditions Buckstalker both in .50 caliber. The Omega has a Traditions (I know, I know) 3-9X40 ML scope and the Buckstalker has a no-name 3-9X40 on it. With a load of 2 50 gr. 777 pellets and a 250 gr. Hornady SST-ML High Speed - Low Drag sabot, they both shoot 1" groups at 100 yards. Omegas run around $350 and Buckstalkers are around $170. I highly recommend either of them.
