I have a 9mm hi-point carbine with a red dot scope. I have used it to take a ton of jacks. I can get on target and nail them fast, it is a really fun gun. I don't want to hear about those of you who think these guns are cheap. Because I don't care, I sometimes get scoffs from friends about hi-point then they shoot it and end up wanting one. I have some nice guns and appreciate them, but if I am going after jack rabbits this one gets the grab 9x out of 10. I was wondering if any of you use something similar a pistol round in a rifle. I have even had this 9mm rifle out calling coyotes saw nothing the times I have had it but would not feel under gunned with it up close. I have shot hundreds of rounds though this gun and never a missfire or hick up. I have never put this gun on paper because like I said I nail what I point at. So does anyone use 9mm .357 mag 40 cal. etc.
