Break Barrel air rifles are very hard to obtain consistent accuracy, due to the barrel lock-up/movement, and, forward/rearward recoiling of the spring/piston. Proper hold (artillery hold) and trigger control are very important as well. After playing that break-barrel game over several years with some pretty expensive RWS's, Beeman's, and a few other break-barrel rifles, and, not wanting to get into the whole PCP world of air rifles, I opted for an under-cocker. With an under-cocking lever, the barrel is always in a fixed position, thus, enhancing consistent accuracy. Some of the best under-lever cockers are the Air Arms TX200, or, the Wiehrauch HW97K. Another top tier under-cocker (which is what I ended up with), is the Air Arms Pro Sport. It's not inexpensive by any means, but, if you really enjoy shooting air rifles, and, actually like hitting what your aiming at, an under-cocking lever (or PCP) rifle is the way to go. I still have my Gamo Black Cat .177 that stays in my barn for rodents and such. But, for some serious shootin', it's my Pro Sport!
