Ideal for pest control

Great for small game hunting

These Gamo shotshells are
Very effective on quick moving targets.
Ideal for pest control where a firearm isn't practical or allowed.
ProsEnough 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.
Best UsesI definitely recommend theses for Short distance small game hunting.. & stopping those fast little pest that used to get away from a single projectile. Or... simply having fun shooting things with a air powered scattergun.

Short range but good four coup de grace

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.

Works well at short ranges

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.
ProsThey do what they are intended to do at close range.
ConsMy 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.

You won't miss! Re-loading single shot non-CO2 allows that possum to saunter away as you re-load
ProsFrom 20-25 feet away a nice 4 inch pattern. Looks good - no missing
ConsNo 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

A better choice
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.

Great pest eliminator.
June 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.
ProsGreat for small pest elimination.
Cons Not much.....

Great Shells!
January 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!

If you have a shaddow express or viper express shotgun there's no way around it, you need these shells. I've been hunting with my shaddow express several times but so far no joy. I do not think these are a particularly effective hunting load for anything bigger than a mouse. That was the biggest thing I have been able to ventilate with these things. I got one unfortunate fellow by my tv last year. since then, nothing. Don't take these shells or the express series guns too seriously unless you are shooting to injure which is not ethical or humane. I keep mine for target practice only nowdays.

Gamo Express EXP20 Shot Shell
June 15, 2010
I love the shot shell. It would be nice if you could reload them or if the price was lower. Gamo should come up with a reloading kit. Maybe a kit that would let you reload with shots or with BB's. I also recommend that they use more shots in each shell.

Shot Shells
September 9, 2009
The Gamo Shot Shells CAN BE reloaded. I've done it quite successfully. To do this, one needs a slightly smaller paper punch (round hole) than a standard ring binder hole. These are available at craft stores.

I cut 2 mm dense hobby foam for the base cup and a piece of parchment-type paper for the front wad using the same hole punch.

Insert the 2mm foam plug in the base, load in 25 or more shot, and cap with the paper. You will need to tamp it with an eraser end of a pencil.

They work well, but one has to not knock them about because the front wad can dislodge with an impact force of sufficient Gs.

I've actually gotten BETTER shot groups by experimentation with the reloads than the factory.

Gamo is missing a trick, here, by NOT providing the tubes and base cups so people COULD do shell loading.

I suppose the lawyers have taken all the enthusiasm out of this...

A little small but...

As advertised, these little guys look quite big, but that doesnt take away from their speed and accuracy. Good product!

the shot shells are pretty good, and make it easy to hit kritters on the run,and I have no dought that they have enough power to take a squirrel out, but I think they could make the shot shells a little bit cheaper, that would definetly get more people to buy the gun and shot shells

This shot shell load helped me rid some garden pests/varmins at 30-35 feet with excellent results, as the shot spread was far more effective than a single BB or pellet, especially with a moving target. I too wish they were re-loadable due to the cost, but there currently is no competition.
By Charlie
OK but not great
April 1, 2007
They're nice but the shots are increditbly small. They certainly soar out of the barrel but I too would like a little more stopping power rather than speed because its definitely not the gun's fault!

At least pack more shots into a single shell. You can remove the plastic cap at the end and pour a few more in and you can pack a few BBs into a shell. Obviously not recomended to personally modify these things but it makes up for the lack of "punch" ;-).

I can say this: I was able to blow a dime sized hole into a milk jug once or twice but it was nearly at point-blank-range and most of the time when trying to re-create this effect I end up with a .22 sized hole or a little bigger.

I hope Gamo comes out with an upgraded version of these things. A reloadable shell that accepts several lead BBs would be good too :-)!

The shell are OK for what I use them for.The only complaint that I have is that the payload should be a little more. I would be willing to sacrifice a little power for a larger payload. A good thing for those of you who tend to loose things( ie the 22 cal adapter) a spent shotgun shell works just fine as a replacement

Outstanding! After years of pigeon crap on cars, walkways, and handrails, I finally have a quick & easy solution to rid the rafters of these pests. A single shot was not always easy or effective, and there was always a chance of fly-aways. Not with the shot from 35 feet, and problem solved. We got 5 in the first three minutes. and quiet as concern about waking the neighbors. I have not seen a single pigeon in twp weeks. Excellent knock down power at a decent range.

Hi. Would I be able to shoot thers through a walther cp88 air pistol? Would they damage the inside of the barrel? Thanks.
By Staff on April 6, 2012

Sorry, these will not fit into the walther cp88

By keitrh from Ft. Collins, CO on November 17, 2011
is it ok to shoot these shot shells thru a rifled barrel.
By Staff on November 21, 2011

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