well I took my time did everything according to the book and how T/C recomends cleaning the barrel, and the procedure to sight it in. Results were 1.5" grouping from a bench no vise at 100 yards. I had a problem getting a good pattern at 150 4". It wasnt the gun but me trying to get a good rest. I would like to put the gun in a vise and see what kinds of groups I could get. Overall Im very happy with the gun, shoots great and super easy to clean. We shot a total of 18 shots. We shot the shockwave 250g and the Hornady SSTML 250g, both shot identical. 150g of T7 and winchester primers. After 18 shots the breech plug came out and turned out with my fingers with ease. So far im very happy....unfortunatly I dont think I have the nerves to be able to put the omega scope to its full potential
