It may be, doesn't have DX mentioned anywhere. If I can do a choke I'll have to lathe the outter polymer off and do a push on or external thread if that makes sense.

I'll do reloaded shells first when I can find the shot. Will use a wad punch and punch some 3mm cardboard for the wadding and will experiment with the front end to keep the shot in. I think overfilled shot will make the difference than doing a choke.

Will keep you posted

Is it worth lathing up a brass choke for the barrel?? If I did and got a 6" spread at that distance it would be an amazing gun for pests

Do you also have the Shadow DX Express? Because I've got that one and I can't see any choke or rifling on my barrel. Haven't really stopped to pattern it, but it feels it spreads quite a bit too. If you get a choke for it, could I perhaps ask for you to make me one too? How would you fix it though, if you wouldn't be able to screw it as you do on a normal shotgun?

On the reloading thing, I ended up buying quite a few shells, but I'm saving the casings to try doing it at some point. Would be great if you could share any results here with reloaded shells. It has about 20J of power, so should be able to shoot bigger pellets than the bird shot at close range.

I will have a look at reloading the shells with more shot and see what happens.

I saw something on the Web about the reason they rifle, air rifle barrels (deablo shape is stable in flight even through smooth barrel)
Was due to air pushing past the pellet as it left the barrel, upsetting the pellet balance at beginning of flight.
spin stabilisation countered that.
It recommended that getting the end of the barrel recrowned on a bit more of an angle and make sure its machined to high standard so the air pushes past evenly as pellet leaves barrel can improve smooth bore accuracy.
Hopefully we will see plenty of starlings and hopefulky a few 2 with one shot. Maybe even a couple on the wing at close range.

I managed to pick up a Gamo viper express last week with 4 boxes of shells. Slightly newer version from my brother in-laws wich was the first version.

My gun does not have the choked and rifled muzzle so probably not as accurate in firing pellets. Also the shot groups are higher at 15m than his gun so they may have set this on the newer version to increase range? Or it might be me... I've missed two starlings because of this shooting high. Will repost once red dots on and hopefully a pile of starlings.

I need to start on the mynars and starlings but havent. I have no idea why. I use a gilly suit during the day which os especially effective with birds. They just dont seem to pick up on it very well. Other critters are getting wise to it.
Im actually out sheridan way.

That sounds quite good, I do some plinking, but mostly hunt too. I've had a permission in a farm near a block I have down in Waipuk for wild turkeys, but the farm has sold last week and now I'm trying to figure out the new owners to see if they're happy for me to carry on taking them down. Til then I'll have to settle with plinking in my own block or using the DOC land for bigger game with my crossbow.

The Viper Express will be likely for varmints around the house, or whatever else I can get short range 😃

thats what i do with them now. Go in with what i want. Will get them to check products for use on air rifles. For example the cyclinder lube I ended up getting I got them to check on web for me as i hadnt seen it before.

Yes, and I've been on the hunt for months now, so they're bloody hard to find here in NZ, and the few ones I've tried to buy - unsuccessfully - had their prices right up there. This one will certainly have its special place in the safe.

Definitely worth I try I guess. I have 3D printers here, just need to figure out how to seal the shells, and if the PLA will withstand the blow.

I'll do some research on Thingiverse to see if I find the 3D model.
