Since you asked for suggestion, here is mine. Stay away from the Wally world offerings and look at the "Our Take" forum on
Straight Shooters. Select a rifle, then click on the Our Take tab. Normally they will give a pretty good evaluation of the product with the pros and cons along with velocity expectations. I personally like the gas ram guns. For the practice you describe, I would suggest a .177 caliber. Some will come as a package with a scope included. Coke can accuracy can be far exceeded by most of the air rifles out there. More like dime-nickel sized at 25 yards. They are quite a pleaseure to shoot.
