Only negative is the effort needed to cock the breakbarrel mechanism. It takes some getting used to.
Overall I am very -leased with this rifle.
I did not use the included scope, for that reason, I saw more things than other buyers.
First of all, this rifle is very good. Still performs different between different kind pellets, but not too far apart. Better than my Crosman Benjamin Trail NP All weather, which was a very pellet specific air rifle........... I zeroed my scope (Aipa Rifle Scope 4-12x50EG Dual Illuminated) by using Gamo Magnum pellet.....not really zeroed, but close enough. When tried some Benjamin Destroyer Pointed Expanding, the shot was not too far off. I was happy to see that result.
It is kind of hard to break the barrel, but after a while, you will start to find it can be slightly easy to be loaded, especially if you do pull down method than push down method.
If you use the included scope, you can stop reading my review now. I have no more to say about. But if you like me want to mound different scope, you will want to read my full review as I went through some thing and realized what I need to buy.
This is the first time I actually lean what a dovetail rail is(the NP trail permanently glued a picatinny rail onto the dovetail, so I did not to worry about anything). I do not know what can a dovetail benefit to a shooter.
1. You need to buy a dovetail to picatinny rail. Be aware that a dovetail is 11 mm (3/8") with curved surface, and the base will convert it to the regular 5/8" (20 mm) picatinny rail. You need this in order to mount your selected scope.
2. You NEED TO BUY A RECOIL STOP FOR DOVETAIL RAIL. Mark my words, you DO NEED to buy one. I did not know the importance until I was shooing on yesterday and felt strange, why the somewhat zeroed scope keep one not being so accurate.....and suddenly noticed!!! My tightly screwed on convert rail almost falling out of my air rifle!!!! The vibration of this air rifle was so strong that it will move your rail backward even if you tightly screwed onto it. You need to buy a recoil stop or use the one on the air rifle in order to stop the movement of your rail. Or you have to find a way to do a pin on the dovetail to stop your picatinny rail.
3. The vibration is very strong, make sure you check your scope screw every each shot. Because....I find my tightly secured screw always got a bit loos after 1 or 2 shots......yes...it kicks that hard.........but you do not quite feel any force on your shoulder. Good for the force damping butt design.
It is hard to cock for me cause at almost seventy years old I'm not as strong as I used to be, but I can get it done due to the added leverage the suppressor length provides.
It is real long gun at almost 50 inches long. I thought the factory trigger settings felt good for me, so have not changed it.
Now for the good stuff. I dialed in the included scope at 50 yards. I was able to place dime sized groups using a "Lead Sled" to stabilize the rifle. I was shooting Red Fire Gamo pellets.
I am 72 years old, 5'10", 160 lbs and in great health. Just not strong enough to cock this rifle without great effort.
Only one complaint - The darn thing is harder to cock than my Hatsan Carnivoir .30, which has actually lightened up some with a couple hundred shots through it now.
hope my new Swarm Magnum in .22 breaks in with same improvement. Although, lets face it. When that field full of crows is found, joy shall overcome effort and recoil!
Gamo Red Fire .22 cal., 15.40 gr. ‚€” Average velocity: 909.24 FPS, SD: 7.42 FPS, group size: 0.51‚€ @ 20 yards & 0.790‚€ @ 40 yards
Most pellets tested were high quality brands, but were not very accurate from my rifle. The quest for the most accurate pellet in my rifle continues.
I have managed to go supersonic with 3 different PBA pellets... two fairly accurate at 20 yards.
Caution: supersonic pellets are LOUD! Almost rivals the sound from a .22 LR. Definitely not backyard friendly.
I did not reach Gamo‚€™s advertised 1300 FPS range, but did achieve 1211.4 FPS with their platinum round (@ 328 ft. elevation).
Subsonic rounds are pretty quite... comparable to my old multi pump .177. I get more noise from my backstop than from the subsonic pellets.
My gun is somewhat hold sensitive: it can be shot equally accurate by any of the normal holds (benchrest and bag, shotgun grip, artillery hold, etc.). However, when switching between holds, my point of impact changes (not the accuracy). Therefore, you need to sight in using the hold that you would be using for your intended purpose (i.e. of hand or bipod for hunting, bench for target, etc.).
Reliability has been very good, no loosening screws or feed problems yet. I love the swarm 10 round clip feature. It greatly improved my enjoyment while target shooting.
