Description

The Gamo Hornet Maxxim incorporates Inert Gas Technology (IGT) into the powerplant by using a gas cylinder versus a conventional spring. That means you get smoother cocking and shooting, no spring torque, no spring fatigue, no issues shooting in cold weather, and a much longer life than a spring powered gun. Not only is this rifle incredibly powerful, but it has many features that set it apart from ordinary breakbarrel rifles with a typical metal spring. The IGT allows you to cock the gun and wait before you take your next shot without worrying about the metal spring weakening. Gas pistons are robust and shoot MUCH smoother, delivering less twang and vibration to the shooter!

New to Gamo is the Whisper Maxxim sound suppression technology. Not only does it deliver a quieter shooting experience, but it also offers even more recoil reduction in addition to enhanced balance and handling.

The ambidextrous synthetic stock has a raised cheekpiece on each side, making this gun ideal for right- or left-handed shooters. The buttpad incorporates the Shock Wave Absorber (SWA) for more recoil reduction. While the gas piston seriously reduces the vibration, the SWA recoil pad stops you from feeling most of the recoil from the remaining movement of the gun.

The Hornet Maxxim is equipped with the Custom Action Trigger (CAT). Light years better than the previous version, you can tailor this trigger to your personal preference. With this smooth and predictable trigger, you'll be amazed at what a great shot you are!

Only Gamo offers the Recoil Reducing Rail (RRR). Designed to subdue the stress on your scope, the RRR absorbs shockwaves and reduces the stress on the internal components of your scope by almost 100%. That equals a longer scope life for you. This rifle is sure to please any shooter who wants precise, quiet accuracy.

Size/weight, Power, No auto-reload magazine

Terrible Accuracy, produces 7" groups at 20 yds on a good day. Chronic Dieseling, smoke in the barrel after every shot, even after thorough cleaning. I never once used flammable cleaning agents. Ineffective "Recoil Reducing Rail" that began to dent or deform where the scope pin inserts (it's made out of a softer metal than the pin). I have put about 500 pellets through it by now, and seeing no benefit from break-in. I am familiar with artillery hold and the mechanics of piston air guns. At this point, the squirrels are laughing at me while they make off with my apples by the bushel. They'll probably turn on my tomatoes next ...TL;DR This gun is not for hunting, unless you dont want to hit what you're aiming at.

I purchased this gun after having good experiences with the .177 Varmints I borrowed from family members last fall & winter. In hindsight I should have just bought a Varmint for half the price, but I wanted something with more stopping power in .22 without the plastic auto-load. Given that I shot dimes with two different Varmint guns at 20 yds, quarters at 30, I have to assume its the gun. Bear in mind, I am convinced I received a lemon based on other reviews, so take this with a grain of salt, but don't assume it can't happen to you. I have heard nothing from Gamo on my warranty claim in over a month.

Accurate and powerful. My rifle will produce dime size groups at 30+ yards. Like I said powerful enough to kill small game. I have killed many squirrels, rabbits, a coon, skunk and a crow. It pushes Hobbie 11.9 grain pellet 803 fpe =17.04 fpe and the H&N Field Target Trophy pellet 712 fps =16.5 fpe. This is a light, easy to carry and shoot rifle. The trigger is nice and light, this is what you want in an air rifle. Gamo has it going on on the barrel lock up system. Some people complain that gamo has a synthetic barrel cover, but they have it so the barrel never comes loose and locks up perfect every time. I have never had to tighten my barrel one time out of thousands of shots, it always stays tight. That is superior technology. I have to tighten the screws on all of my other spring rifled barrels.

Maybe open sights would be nice. Nothing else.

You don't need a 1000 fps rifle to be effective and deadly on small game.
Yesterday I shot a rabbit through the neck and out the chest, dead right there, power to spare.
I own several break barrel air rifles, a Walther Parrus 22, Hatsan125 .25, Weihrauch HW80 .22 and they are more powerful than the Gamo Hornet Maxxim 22, but the Gamo is easiest to cock, super fun to plink with and I don't get worried about scratching the stock like I would with my HW80. Fun without the worry.
Plan on putting a tin of Crosman Premier Hollow Point pellets through it. $6.24 for 500 pellets at Walmart. Happy shooting.

I have re-chronographed my Gamo Hornet Maxxim 22 in front of a mirror to keep the barrel level with the chronograph to give more accurate numbers. Come to find out that the rifle is in the magnum class for air rifles. The Hobby 11.9 grain pellets shoot 829 fps, 18.16 fpe and the CPHP 14.3 grain pellets are shooting 757 fps, 18.27 fpe. It is no wonder that I was able to put down the skunk and racoon.

I've purchased 3 all in 22 caliber. On first one, I learned how accurate this rifle is IF you clean the barrel BEFORE attempting to site in scope/ gun. Once clean, had quarter size groups at 30yd. I've hit targets 90 ft high in trees and well over 50yds linear distance, felling them as plenty of power. Seems GAMO has got game. This rifle is probably the best value for the money in nitrogen piston arena.

Better scope, although it's adequate

Excellent one piece scope mount.
Found that JSB Match Diablo exact 18 grain 5.52mm take full advantage of power plant, seat tightly, and are more stable, consistent for this rifle vs lighter pellets

Lightweight. Shoots good and accurate. Not bad Scope when compared to others that are included with Gun.

Put some Black Paint on Metal Trigger so it matches the Gun. Would have saved me doing it.

A worthy Gun to add to your collection.

Cocks easy enough, feels comfortable, about as quiet as I expected, haven't found the right combination of pellets but fairly accurate.

Advertised for small game and plinking, Plinking is great, but only pisses a squirrel off. Maybe not the right pellet yet. Hollow points aren't working.

There is no adjustment to the trigger as advertised or mentioned in owners manual. Set screws are bottomed out and tight, cant turn in to adjust.

Ran outta text so part deux: I don't know about the trigger since I think it's newer that I've seen. It may be that you need to unscrew it to adj the two stage part? On mine, and most any others, you have to find the ideal spot in the middle somewhere. When adjusting it helps a lot if there's no anti-bear trap safety device, which is one of several reasons I toss those in the trash. If removed I can cock the gun, let the sear hold the piston so the barrel is still in the cocked position but limp. Then hold the barrel with one hand in preparation b/c when the trig is pulled it'll try to get away from you via the full spring force. If it does get away it'll bend the barrel upon closing. So then you pull to feel where the trig is, when it releases you simply pull the barrel back a few inches and repeat. Be careful adjusting b/c safety or not people have caused it to fire during adjustment! Always be wary! Also, too short of trig pull adj can cause it to fire all by itself w/o warning!

Usually hollow point pellets don't work. Like the old saying; "There are two kinds of fishing lures; the kind that catch fish and the kind that catch fishermen" It applies to pellets and most are useless. In 177 guns between 12 and 20ftlbs power I'd say the best choice is the H&N Crow Magnum. See video: https://www.youtube.com/watch?v=X3Lp9s1TNyc Note the picture of the pellet at ~35sec mark :o There's newer stuff like the Baracuda Hunter Extreme but they need more speed and open later so not a good of a match for you. Predator Polymag have good reviews for opening but I've never tried 'em. If yours is .22 then they Crow Mag will still likely work better than any other but the velocity will be less than ideal. So in 177 I consider Crow the pellet to use on Rabbit or Crows and smaller. I prefer it over any pellet in 22, assuming the same power. Otherwise I'd try (in 177) JSB 8.44, 10.34 and maybe 13.43gr, and H&N Baracuda Match. In 22 I'd try JSB 14.3, 15.9 and maybe 18.1.
