^ This! ^the 4.62 is optimum, IMHO.
Send it back, and maybe they can fix it.I hope you folks get better accuracy than I get with my Wrangler. I can‘t leave a hole in an 8 x 10 sheet of paper if I shoot a five shot group. The first shot will make a hole, but the following four will go through the first hole, sucking the paper in behind it. By the time the fifth shot is fired, the vacuum of the bullet will completely close the hole by sucking the paper in behind it. 🤥
Solar powered, of course.Do you by chance have a flux capacitor taped to the barrel to get type of performance? 🤔
