I also bought a new 25 caliber air gun not mentioning what brand it is but also not knowing I needed a pump for the gun my mistake but just saying if you're going to buy these high-dollar air rifles check into it more than I have because it's been a costly mistake.

Gamo portrays these 22 caliber shells to work in a 22 caliber air rifle not true what so ever as far as I can tell unless I'm missing something. Can anyone help? I have a Gamo Whisper Fusion Mach 1 22 caliber and the shells don't come close to fitting and they are 22 caliber shells. So why? Help me out please.

Not enough info or misguided by Gamo.......IDK.

These Gamo shotshells are very effective, Ideal for pest control

By JamesUSAMarch 21, 2019 Verified Purchase

These Gamo shotshells are Very effective on quick moving targets. Ideal for pest control where a firearm isn't practical or allowed.

Enough payload & velocity to stop small pest in their tracks... without destroying the surroundings. No (powder burning).. So its Quiet enough not to disturb the neighbors. I was very Impressed & amazed at the consistent shot patterns from these little shotshells.

I wish for a little more range, or a a little heavier shot load, but once you have tha "bushy tailed rat down it offered a good finish...doesn't ruin too much meat.

By FredUSAJune 7, 2018

I have used these in my Gamo Viper only a little bit so far. I have checked the patterns at 10 and 35 feet and they put enough pellets on the target to do enough damage to small critters even at 35 feet. I would say that is the furthest I would use these.

They do what they are intended to do at close range.

My only complaint is that I feel that there should be more shot in these shells which is why I gave 4 out 5 stars. Considering the length of the shell there is very little of it used for shot. More could easily fit in the shell.

great for killing flies

cool just too small

too small

By Dave T.January 5, 2015

You won't miss! Re-loading single shot non-CO2 allows that possum to saunter away as you re-load

From 20-25 feet away a nice 4 inch pattern. Looks good - no missing

No real distance but you can't have it all. I don't think any other gun so far uses that ammo. The ammo was back ordered at first which worried me but then it was delivered later the same day the rifle arrived. Buy plenty of ammo then it will be a non-issue

By Richard B.June 12, 2014

You can get 12 ga with #9 or #12 shot that works way better than these and are cheaper and fire out of a real gun. If you live somewhere that you can't shoot a real gun out of your back door you live in the wrong place.

By KyleUSAJune 13, 2012

Very effective at close range (30 ft). Which is perfect for the pest elimination I need. 100% kills at that range on 20+ targets. Would not recommend for anything larger than a small squiril.

Great for small pest elimination.

Not much.....

By DrewJanuary 5, 2011

I dont know why everyone says these arent powerful...these are outrageous!!! I have killed a squirrel from 15 yards away drop instantly i have killed many rabbit with this and dove and quail hunting around here is so much fun with this its the perfect shell. You actually can reload these go on youtube and look it up these shells were expensive but im gunna get a few while there one sale seriously you need these. After all the only reason everyone buys this is for the shotshells!

Are the shells reusable ? Can you shoot skeet clays with them?

asked Kevin from USA

Will this fit into the Gamo Shadow express?

asked Elijah

What kind of ammo do I load with?are they reusable? Where do I get the ammo if they are reusable?

asked tyler Huntwork

Si pero no duran mucho lo mejor es mandarlo a un tornero o herrero y que te aga alguna en aluminio asi duraran para siempre

ismael from USA

Would these shells be effective against small to medium snakes? I live in a residential area where we aren't supposed to discharge firearms and I'm thinking something relatively quiet like and air rifle might be a way to dispose of the occasional snake without alerting the neighbors to what I'm doing. I had thought about something like a .22lr shot shell but they are still fairly loud...

asked Bryan

Why would you want to live somewhere that you can't discharge firearms?

Richard Bendover

I use these shells to remove sparrows from grocery stores and they are very effective at close range (10 yards or so). Since a birds skin affords a lot less protection than a snakes scales I wouldn't think they would be effective on anything more than the smallest snakes. BTW, In our state it is illegal to kill any species of snake so check your local regulations first.

John from USA

I was looking at the reviews the gamo express shot shell, i was wondering if the shells would work with any other .22 caliber rifle besides the gamo express?

asked connor

The empty shells will work like the brass adapter, but there is a lip at the base of the shotshells, where the brass adapter has no base. So with the base being smaller than a .22 pellet, either you remove the lip at the base of the plastic shell to make yourself an adapter for a pellet, or you would be able to push in a pellet or a round ball would be easy to push in. That also would work.


No they would not work. The shot shells are larger in diameter then a 22 cal. pellet. The rifle made to use the shot shells are not rifled and when a 22 cal pellet is used, an adaptor must be inserted in to the chamber. Then a 22 pellet is then inserted in to the adaptor.

Ray from USA

when do you think you will have the Gamo Ezpress EXP20 Shot Shells in stock I want 3 boxs please let me know

asked ozell taylor

Scott from USA

Can the casing be reloaded with say #6 shot?

asked bobby

Yes. Go to Michael's hobby store and buy some small cotton balls. I believe they are 2mm. Stand the shotshell up on a flat surface. Put one ball in and tamp it down with a dowel or something. Put in any kind of BBs you want. I use #6, 9, even bb's (2 or 3 only) or even rice -- anything you want to shoot. Fill it up a little over half way and put another cotton ball on top and tamp it in. You're done! You will soon know how much and what to put in the shell. The lighter the load the higher the velocity. Also you can buy aluminum casings on the internet. They are the best and last forever. Make a little dipper to make the loading faster. I have many airguns; this one is best.


I would imagine #6 can be put in the shell case however they are larger and heavier than the much smaller and lighter factory stuff, you will lose power/speed and very few shot due to space occupied by the larger shot. Probably not a good idea.


Sure. Use biodegradable packing peanut material as the base wad. That stuff is not styrofoam. It is natural. Get it wet and it gets sticky, that's an easy way to tell you have the right stuff. Pinch a decent piece off of one of the peanuts, and pack it in an empty shell so it is about 3/16 to 5/16 thick at the base when packed. Then get your shot, mix with some sawdust and cap with a piece of wax paper tamped in. Don't tamp the sawdust/shot really tight, The performance of this recipe is quite good and will allow you to reload your shells till they crack, which they will. You can get metal ones via the net that a guy is making and selling too.


Hi. Would I be able to shoot thers through a walther cp88 air pistol? Would they damage the inside of the barrel? Thanks.

asked Henri

Sorry, these will not fit into the walther cp88

Steve from USA

is it ok to shoot these shot shells thru a rifled barrel.

asked keitrh

Hi, these shot shells should not be fired through a rifled barrel as the shot could damage the rifling of your airgun. Thanks
