What steve says is correct if your in the UK then that is a firearms cert. air rifle - if you are not in the UK then you should check your regulations on the power regulations for air rifles

 

As for your questions changing the barrel on its own should not give a rise in power like that, changing the internal mechanism workings would -

 

But it is completely possible for an air rifle to put out that much power (the american market is full of really high powered air rifles)

 

As for pellets - probably a heavy domed pellet would suit the rifle (with that much power aslong as you can hit the animal you will kill it)

I was always under the impression that a longer barrel (to a degree) will up the power as it makes it more air efficient. It will certainly increase shot count

Yes cause he also brought a hw100 and it has a short barrel and he says that if its power is increased then its shot count will decrease and he does not have a longer barrel for it,so it remains sub 12.

[Tron 173]

Increasing the barrel length on a PCP will give more power within reason, IE, replacing a AA400 series Carbine barrel with one from a Classic can put up the power quite a bit. only downside is the extra length making it a bit unwieldy in the field or a hide,by comparison shortening a springer barrel makes no real difference to velocity again within reason.

 

Edit for spelling mistake.

I agree that changing the barrel length does affect the power and shot counts,

 

longer barrels use less air (to achieve the same fps compared to a shorter barrel) and allow for an increase in power due to the pellet being accelerated for a longer time ( to a degree if the barrel is too long it has a negative effect)

 

However the super 10 you have is putting out just shy of 24ft lbs With the 14.3g,

 

What I was tying to say was I didn't think you would get that much of a power increase just from changing the barrel.

24 foot pound sounds like an export regulator has been fitted IMHO! Take the action out of the stock (remove air bottle, trigger guard screws and the one in the fore end), lift action out of stock, examine bit that air bottle screws into, if it says "Export only" you are in the crap!

 

I know, been there done that!

It looks like a 19" barrel similar to the one someone used to clock mine,it's currently getting chopped by xtx to 10'5" having used chair gun to do the math's this will give me 11ft/lbs coming off the bottle instead of what it was doing.

Using a 15fps reduction per inch shaved,times it reduce the mv by that and that's where I wanted to be.Do it the other way and even the Export 24" barrel wouldn't get you where you are,you'd need an export spring,thicker wire!

Everything else on mine has been replaced with new parts,Spring,Spring Guide(brass,for longevity),Transfer port(chambers sent me a big bore as a uk power 16 joule?in with a cleaned up old one!).

Just waiting on the barrel to rebuild and enjoy!!

[superten.177 0]

Probably should mention,yes the barrel is the best source to increase the power,there's not much difference between so called fac reg's and standard uk power reg's.

It's a small change made with the shim's in the reg to differentiate between .177/.22.(fac upto 28ft/lbs IS the same reg)

The true FAC reg came about in about 2000 for the mk3 because of the yank's wanting 35/40 ft/lbs,hence Bowkett made an upgraded one for export!

So barrel and spring!!

I'll probably get banned,but I'm sick of the mythology surrounding s10's.

_{I might be wrong but that S10 dosent seem to have the correct air cylinder fitted? certainly all the BSA S10 guns I have seen have a air bottle fitted to power it that gun seems to have a tube cylinder fitted instead. unless of course its a model for the USA market.}

 

Is it a Stalker variant

[pro extreme hunter 10]

It looks like the gun is in good in power went for hunt using jsb exact jumbo 16g and got good result at reasonable range

[kanny 20,619]

good result i was looking at the jsb,s also i think i might give them a try what kind of range was you getting the doves at?

Thanks Kanny ,the range were 50 yards approx the two that got away were at 60 to 65 yard ,thinking of using lighter pellets for better trajectory 14.3g pellet is 860 on this gun what do you think .The gun is giving tight groupings at 50 yard with almost all the pellets i tried even the gamo pellets were doing well.

im no expert on the higher power air guns but wont the lighter pellets become abit unstable with that much power behind them? nice shooting by the way

correct it will do that in most cases

I am thinking of lighter pellet for flat trajectory at max zoom ,right now my gun is zero at 40 yard with jsb 16g but at max zoom from 25 to 30 yard range the pellets goes about 1 inch high more speed will hope fully flatten the trajectory.Thats according to charigun software.Will try it soon.

like you say the best thing is to just try it dont forget to give us your verdict here

Tried the defient 14.3 g pellets and the results were great at 12x zoom 43 yards zero and its the same at 30 yard plus half a meldol hold over at 55 yard will update when try it further down range.
