I have been shooting high-end pellet guns for many years. This one, although I didn't figure it to be a high-end gun when I purchased it, is outstanding. It is as good, if not better than the many other pellet guns I have in my collection. Dollar for dollar, I feel it is way better than many of them. It is easy to arm, easy to load, and allows multiple shots with the 10-shot magazine. Very accurate and very light.

The Gamo Swarm Fusion 10X Gen 3i rifle is fantastic. It takes 30 pounds of force to cock it but is very manageable. I am 71 and in good shape but glad I chose this gun instead of the big brother Magnum version that requires 30% more power to cock it. This 22 caliber rifle blew pellets right through a 3/8” OSB backstop. Switched to a backstop of 3/4” 5-ply plywood, the rifle fully imbedded the pellets but they didn’t penetrate all the way through. PLENTY of power for squirrels and any other rodents you may wish to dispatch. The targets above are from my second session with the rifle, the first after sighting in the scope. No bench or bench rest, just sitting on the ground using my knees for support. Gamo pellets, the Hunter impact 15.43 gr at 75 feet were decent. The Red Fire 15.4 gr were definitely more accurate, although it could partially be attributed to my getting used to the trigger pull. ( Before yesterday, it’s been a few years since I shot a rifle.) The 30 foot target is the range I estimate to my bird feeder, where the squirrels have been harassing my feathered friends. The 3-9x scope that comes with the Fusion is very good. The only con I have is that I have to break open the barrel to remove the scope covers or to put them back on. The front cover will just about but not quite slip by the breech platform. Small thing and I would rather break it open than loosen the rings and reposition the scope. (The base of the scope is anchored by a recoil pin and the barrel mount can’t be moved any further back when mounting the scope to the gun (but the screws on the rings can be loosened and the scope moved further to the rear. )). Definitely a 5 star product, I am very pleased with it. The gun is also quiet. Makes about as much noise as an air nailer. The pellets make more noise hitting the backstop than the gun does spitting them out.

The only gripe I have with it is that I was unable to use my laser bore scope on it, due to the flair and noise reducer at the end of the barrel. I had to zero it the old fashioned way. Once I did though, my shot groups were nice and tight, and it held accuracy through many many shots. It is pretty quiet, using my sound meter the highest I saw was 94db...which is not bad considering how powerful it is. The 10 pellet auto loader is a nice feature and works great.

I finally bought this gun after looking at it for over a year. I've read all the reviews, good and bad. So far, I'm not finding the issues that people complained about. It always amuses me how many people will write a review without giving a product a realistic trial. There are so many variables that needs to be taken into account.Quick summary. I love the speed load magazine. The main reason I waited for this gun. The Gen2's mechanism gave me the option to use gun's very good iron sights. Iron sights are great to have and too often excluded from guns that bundled with a scope. Power is good enough for pest disposal. Don't worry about FPS. Muzzle energy is more important and this gun has plenty. Sound is not too loud but will seem loud because your head will be right next to the spring piston bang. If you're more than a few feet away, it's quiet enough to be backyard friendly, especially with heavier pellets. Very comfortable to hold but it's not light 8 lbs fully spec'd and loaded. Sling mounts would've been nice for hunt hikes. Not too heavy to cock/break the barrel, 30lb or so.So accuracy first. It's important to understand that this is a gas piston/spring piston, break barrel rifle. And with such, it's going to be different for most shooters upgrading from the pump guns from our youths. The recoil will be different and your hold will need to be different. I did have to deal with that learning curve. YouTube Artillery Hold for a better understanding. Start with getting your practice in with the iron sights to really gauge out of the box accuracy. And make sure you try a few different pellets to find one your specific rifle likes. I've shot 4 types of Gamo pellets ranging from 14 grains to 22 grains and have been able to group them easily.The scope sucks but fine for a beginner. Tried it for a couple of weeks and just didn't like it. I really wanted adjustable objective and Mil Dots, features this stock scope didn't have. So I upgraded. Just make sure you get a scope same or shorter than the stock scope because the 10X mechanism will limit how long the front of your scope extends. I went with a UTG Hunter but the UTG Bug Buster may have been better size-wise. Take your time zeroing in and remember the springers/pistons are really harsh on scopes. Tighten all screws every once in a while, on screws and the gun. Once the scope is mounted, take your time to understand flight trajectory and practice practice practice10x Magazine has been fine for me. I bought an extra so I'm always at the ready. I have had maybe 2 pellets fail to cycle properly. I bought the Gamo combo pack which includes the Hunter, Master Point, Magnum and TS-22 pellets. I shot all these pellets using the magazine and they loaded and cycled with no issues. Even the Magnum which says not recommended for repeaters has cycled flawlessly. Just remember not to leave them loaded too long since it is spring operated.Overall, I'm happy with the gun. Would've preferred they keep the scope and made the gun $20-$30 cheaper. Oh well, now my son has the coolest scope on his Nerf gun, haha
