The Crosman 622
by Paul Hudson
The Crosman 622 is a rarity — a slide-action CO2 repeater.
The Crosman 622 is a repeating slide-action CO2 pellet rifle. It was produced from 1972 to 1978 in .22 caliber only. It uses the familiar 12-gram Powerlets and has a rotary clip that holds six pellets.
There have been only a few other slide-action repeaters available in the recent past — the Gamo Extreme CO2 and the Shark roundball repeater made in Argentina are two examples. The Gamo uses an 88-gram cartridge, and the Shark is a bulk-fill gun.
This particular 622 belongs to my brother-in-law’s friend. It had not been fired for many years and was in need of a resealing. The old factory lube had turned to hard wax, and several hours of cleaning was required to get everything in working order.
Due to its design, the 622 did not develop a reputation for durability. The valve body is made of two parts held together with a single screw and is prone to breakage. A second bolt or pin can be added to the bottom of the valve body to greatly strengthen the assembly. Another problem was the tendency for the gun to jam with certain pellets; this can happen if the muzzle is elevated when the slide is cycled. Some pellets (depending on their shape) can back out of the clip enough to prevent it from rotating. Keeping the gun pointed down will help prevent this. Possibly due to this problem, Crosman added a lever to the receiver of later 622s to aid removing stuck clips.
There are many parts in the 622′s receiver. The large, rectangular casting on the right is the valve body, and it’s prone to breakage. The probe is near the top of the receiver and is in the rearmost operating position. In the middle is the rotating rod that advances the clip. The large cylinder on the bottom houses the striker.
The 622 is large enough not to feel like a toy. It’s 40.5 inches long with a 13.5-inch length-of-pull, so it’s adult-sized. The blued barrel is 23 inches long, and the gun weighs 6 lbs. without a scope. A square post front sight and a square notch rear sight come from the factory, and they’re entirely suitable for the ranges at which the gun would be used. The painted receiver is made of two die-cast pieces and is grooved for mounting a scope. While the paint isn’t the greatest finish, no complaints can be made about the blueing on the barrel and gas tube. It’s very well done for a low-priced gun. Both the stock and forearm are made of varnished hardwood that has a very straight grain. The receiver is only about an inch thick, and the gun does not feel bulky; combined with the light weight, it’s a perfect plinker and can be carried for hours.
The rear sight is a simple square notch and is adjustable for elevation and windage.
The front sight is a square post. The ramp is textured to prevent glare.
A manual safety is mounted behind the trigger; it’s very similar to the unit on many other Crosman models. The single-stage trigger was a pleasant surprise. It isn’t adjustable…but it’s fairly smooth, mostly creep-free and breaks at a consistent 2 lbs., 2 oz. For an inexpensive airgun, it’s quite good. Holding down the trigger while cycling the action lets the striker travel forward with the slide; it will not fire the gun.
The trigger features Crosman’s typical cross-bolt safety and is surprisingly good.
The rotary clip
The 622′s 6-shot rotary clip is easy to load and fits entirely within the receiver; it will not interfere with a scope or catch on anything during handling. Unfortunately, the clip accepts pellets with a max length of 0.275 inches. This prevents longer domed pellets and pointed pellets from being used. All wadcutters fit, and most cycle fine.
Rear view of the clip. Pellets load easily from this side.
The thin clip will not accept pellets over 0.275 inches long. The Baracuda Hunter is about the longest pellet that fits.
To charge the 622, the end cap of the lower tube is removed. A CO2 cylinder is dropped in nose-first (don’t forget a drop of Pellgunoil on the tip), and the end cap is replaced. As the cap is tightened, a slight hiss will be heard as the cartridge is pierced. Further tightening should not be needed. Since the CO2 cylinder seats against a flexible seal, it should be removed after shooting. A single cylinder was good for 36 shots, or 6 full clips. A two-cylinder lower tube, similar to that of the Crosman 160, was available for a time; but this was an aftermarket part not supplied by Crosman.
A single CO2 cartridge is used in the long gas tube.
The 622 was rated by Crosman at 450 fps; this gun exceeded that rating with all tested pellets. The temperature was around 90 degrees during shooting.
MV=muzzle velocity (fps), ME=muzzle energy (ft-lbs), ES=extreme spread (fps)
Getting the best accuracy from the 622 is a bit of a challenge. The forearm uses a single operating rod and can slightly rotate around the lower tube. This allows the gun to move upon firing if it’s held by the forearm. For best accuracy, support the 622 just ahead of the receiver by holding the gas tube. This is really a minor point; the 622 is not a long-range target gun — it’s a plinker, and one of the most entertaining ones at that.
10-meter groups with open sights
All pellets tested were more than accurate enough at 10 meters for plinking and informal shooting. Groups are 6 shots since that’s the magazine capacity. Here are a few of the best performers:
25-yard groups with a scope
The factory open sights just aren’t precise enough to produce the best accuracy at 25 yards. I mounted a simple 4x Leapers scope for these groups. Most pellets gave groups in the inch to inch-and-a-half range. There were a few standouts, however:
While the 622 isn’t the best engineered or most accurate airgun Crosman ever made, it’s still an interesting piece. There have been only a few slide-action airguns produced; and for plinking, the rapid-firing provided by a slide-action really ups the fun factor.
Many 622s are still in circulation, and they regularly show up at airgun shows and on auction sites. Lack of attention from collectors has kept the price reasonable. One caveat is to make sure the gun includes the clip — they fetch about 25 dollars apiece. It’s possible to load the rifle singly, but it’s tedious.

Today, blog reader Paul Hudson shares his Theoben Crusader rifle with us. The Crusader is not as well-known in the U.S. as some other Theoben models, so this will be an interesting report.
If you’d like to write a guest post for this blog, please email us.
With its walnut stock, the Theoben Crusader is a large, handsome airgun.
The Theoben Crusader is a high-power breakbarrel airgun, identical in size and performance to the Beeman R1. Its stablemate, the Theoben Eliminator, seems to get far more press since it’s one of the most powerful breakbarrel airguns available. That power comes with a high price — a cocking effort of 50+ lbs. — that most shooters are not willing to endure for very long. The Crusader, on the other hand, is far easier to cock and is a more practical airgun. Based on the used guns I’ve seen for sale, either the Crusader sales are much lower or people tend to keep them. Few are seen on the usual airgun sales sites or at airgun shows.
The Crusader is a high-quality spring-piston rifle.
Measuring a full four feet in length and weighing 8 lbs., 3 oz. unscoped, the Crusader is a large airgun. Mine is .177 caliber; but .20, .22, and .25 calibers are also available. The Lothar Walther barrel is 16 inches long, and a muzzlebrake is standard equipment (.22-caliber Crusaders have an Anschütz barrel). There are no baffles in the muzzlebrake. No open sights are supplied by the factory, making an optical sight a necessity. My rifle has a right-hand walnut stock, but an ambidextrous stock can be had from the factory as a no-cost option. The pressed checkering does give enough grip to be functional. A very good non-slip recoil pad keeps the rifle in place. No plastic parts are used on the rifle.
The metal work on the Crusader is first-rate, with a high polish that’s typical of many British airguns, and the wood-to-metal fit is excellent. Allen-head screws are used throughout the gun except for one screw that secures the triggerguard.
Behind that screw, a Schrader valve allows the owner to change the air pressure in the gas spring. Note the thumb rest in the stock.
A gas spring
Like all Theoben springers, the Crusader uses a gas spring, not a metal spring. Cocking is butter-smooth and requires 38 lbs. of effort. The piston includes a sliding weight that reduces piston bounce and felt recoil. A Schrader valve at the rear of the receiver allows the pressure in the gas spring assembly to be adjusted to vary the power of the gun. Upon firing there’s no spring twang or vibration, just a quick snap. The sound level is moderate. And, due to the size of the gun and careful tuning, the felt recoil is mild for the power level.
The lower bolt is pinched between the breech block and the locking wedge to prevent vertical barrel movement. Note the taper at the rear of the barrel to make pellets easier to seat.
The barrel pivot setup on the Crusader is a little unusual. Most breakbarrels use a breechblock that’s close to the width of the forks of the receiver. Wide, thin shims may also be present between the breechblock and the receiver forks. The pivot bolt is then tensioned to the point that the lateral barrel movement is constrained. The breechblock on the Crusader has much more side clearance. Belleville washers are used to control the lateral movement. Belleville washers are cone-shaped from the side and are actually considered to be springs. A second bolt behind the pivot bolt mates with a hook on the back of the breechblock. The locking wedge pulls the breechblock tightly against this bolt to control the vertical movement of the barrel. Like many classic Webley rifles, the Crusader takes a bit of a slap to open the barrel for cocking.
The unusually wide breechblock/fork clearance is visible from below the action. (The photo is overexposed, leading to the yellow stock color. This was necessary to bring out the detail within the cocking slot.)
The Evolution trigger of the Crusader and other models has been criticized by some; and given the price of the gun, that may be justified. No creep is felt in the first stage, but the second stage is not as crisp as a Rekord trigger. As the gun came from the factory, the second stage breaks cleanly at 1 lb., 13 oz. The safety blade resides in front of the trigger and automatically sets when the gun is cocked. It can also be manually reset. Overall, I would rate the Crusader trigger as very good, just not quite as good as a Rekord or TX200 unit but not a reason to avoid the gun.
The trigger blade is almost straight; the automatic safety resides in the front of the triggerguard and is pressed forward to fire.
Velocities with the Crusader are similar to what’s found in a Beeman R1, and some lighter pellets in a .177-caliber rifle will go supersonic and ruin the accuracy. I tried a couple H&N Field Target Trophy Green pellets, but they traveled almost 1200 feet per second and missed the bullet trap at 25 yards. Extreme spreads with most pellets were under 20 feet per second, and a few varied by less than 10…very good for a springer.
These are the velocities the Crusader can deliver with the selected pellets.
Many pellets gave 5-shot groups around an inch in size at 25 yards. Several gave very good accuracy, including a few that surprised me. To get the best accuracy shooting from the bench, I had to hold the airgun loosely with my right hand and keep my left hand open. If I let my fingers touch the forearm, I had to make sure I didn’t squeeze the gun at all or the groups would open up. In other words, use the classic artillery hold. You cannot grip this airgun tightly and get good accuracy; it’ll take practice and proper technique to get the best results.
All groups were 5 shots at 25 yards, and the sights were not adjusted for the different pellets. It was interesting to see the difference in the points of impact. Predator Polymags and 8.4-grain JSB Exacts shot especially high in relation to the other pellets. Unfortunately, neither 7.9-grain Crosman Premier lites nor 10.5-grain Premiers heavies did much better than one-inch groups at 25 yards. While that’s not too bad, a number of pellets did far better.
Five H&N Baracuda Hunters made this 0.50-inch group.
Five Predator Polymag pellets made this 0.40-inch group. Good enough for hunting.
Gamo TS-10 surprised me with a 0.45-inch group; but their size seemed a bit inconsistent, and there were some flyers with this pellet.
Skenco Big Boys gave this nice 0.43-inch group. The group is almost twice as wide as tall.
The 13.4-grain JSB Monster also produced a 0.43-inch group.
The Crusader really liked the 8.4-grain JSB Exacts, as this round 0.24-inch group shows.
Best accuracy came from the Beeman Kodiak pellet. This group above is just 0.23 inches.
Adding it all up
Why buy a Crusader? After all, it costs just over $1000, and that price will keep many away. Compared to a Beeman R1, the size and power are identical. The R1 has a better trigger, but the Crusader has a better firing behavior due to the gas spring. The Crusader also has a far nicer stock, better metal finish and includes a factory muzzlebrake. Between my Crusader and my R1, the Crusader shoots more pellets accurately and will shoot slightly smaller groups, probably due to the fine Lothar Walther barrel. Unfortunately, the Crusader is more hold sensitive than my R1.
Both rifles should last a lifetime with proper care. It’s possible to upgrade an R1 with a new stock, a gas spring, muzzlebrake, etc., but you’ll end up spending more than the cost of the Crusader and still do not have the nice metal work. If you can afford it, the Crusader offers very good accuracy in a nicely finished package.
Theoben Production ceases
In October, 2012, Theoben Ltd. in England announced that they were entering liquidation (bankruptcy). It remains to be seen whether another company will take over production rights for Theoben springers.
