    I purchased my GAMO SWARM MAXXIM 177 CAL. JULY 2019. I NEVER THOUGHT I WOULD EVER ORDER ANY GUN WITHOUT HOLDING IT AND LOOKING IT OVER. IM VERY GLAD I DID. THE GAMO IS A VERY WELL MADE RIFLE AND VERY ACCURITE. THE SCOPE WAS VERY EASY TO SIGHT IN. IT WAS A FEW INCHES HIGH AND TO THE LEFT. I HAD THE ADJUSTMENT CAPS OFF AND HAD BULLSEYE’S IN THE SECOND MAGAZINE. I HAD ORDERED 2 EXTRA MAGAZINES. I MADE A BACKSTOP OUT OF HEAVY WOOD AND THICK ENOUGH I WOULD KNOW IF A PELLET EVER MADE IT THROUGH . I TOOK ROOT BEER CANS AND I TAPED THE EMPTY CANS TO THE BACK STOP. WITH THE PULL TAGS STRAIGHT UP I PUT MASKING TAPE OVER THE TAB AND TOOK A RED AND BLACK SHARPIE PENS I MADE THE TOP OF THE TAPE WHERE THE HOLE IS I COLORED BLACK AND THE BOTTOM HOLE I COLORD THE TAPE RED OVER THE HOLE. I HAD MADE A CONTAINER OR RACK THAT FIT THE GAMO FOR A NICE FIRM HOLD. I MEASURED OFF 60 FEET AND SET THE CONTAINER ON A CARD TABLE AND I HAD A CAMP CHAIR TO SIT ON. I FIRED 4 PELETTES AT THE TWO CANS AND PUT 4 PELLETS THROUGH THE TAPE AND RIGHT THROUGHT THE ORIGINAL HOLES IN THE TAB.EXCEPT FOR ONE. I SHOT A HAIR LOW AND MADE THE ORIGINAL HOLE A LITTLE BIGGER. I WOULD RECOMEND THE GAMO BRAND TO ANYBODY. I’LL BE 84 VERY SOON AND THE ONLY HARD PART FOR ME IS COCKING THE RIFLE. THE RIFLES SAFTEY IS THE BEST I’VE SEEN,. NO REASON NOT TO USE IT AND I WOULD RECOMEND TWO EXTRA MAGAZINES. R.W.
