air rifle power and pellets

[cleversquirrel 0]

I do find it anoying that you can legally buy an air rifle but you have to be very carefull which pellets you use!! Not everyone has access to a chrono and personally I dont think it should be the rifle owners responsibility.

 

But thats just my friday rant!! hahaha!!

 

 

Its the gun shops responsibillity to sell you a legal gun but as soon as it leaves the shop the responsibillity is all ours to ensure we dont break the law.

Good point Mal perhaps a warning on pellet tins would be a good idea.

At least it would make people aware that it is possible to alter the mv with just a change of pellet brand/type!

I understand that mate but if you dont tamper with your gun in any way, why should we have to be carefull of what pellets we legally buy?. I agree with the pellet tin sugestion, there should be warnings on the tins of pellets that could cause your gun to go over the limit ie. when the pellets are very heavy.

Agree with Logun here.

Should be down to the manufacturer to 'set up' 12ftlb rifles to just that.

I know Falcon used to test with Bisley magnums to get just under 12ftlb.

Pretty sure that lighter pellets will produce less ftlb?

So as has been said set up with the heaviest to just under the limit and you should be safe.

Unless lilly law has got PMT

 

It's heavier pellets=more power for springers & less for PCP I think?

 

You'll never get a manufacturer to check every rifle with every pellet, if they did the cost would rise massively.

 

I suppose if this did happen folk would then complain that their rifle was underpower with their favoured pellets.

 

A gun shop sold my mate a HW95 that was putting out 13.5 ft/lb when chrono'd. It was soon rectified

found this from a past topic!

 

Reverses the last theory!

Probably been around before but how is MV affected by pellet weight?

ie if a gun produces 12ft/lb with Bisley Magnum (21.4 grain) what would it be with Air arms field at 16 grain?

Is it a relative thing?

 

reply from bill88

Generally speaking a heavier pellet will produce a higher ftlb's figure than a lighter pellet,although the reverse is true with a spring powered gun.

A bisley mag weighing 21.4 grain leaving a pcp at 502 fps will be almost exactly 12ftlbs,therefore a 16 grain pellet at the same velocity will be producing 8.9 ftlbs.HTH'S,Bill

I have a HW90 .22 and I have had it years and never had it tested.

 

Is there a cheaper way to do it than buying a Chrono? The cheapest I can find is £40 which is no laughing matter when your a student without a job.

[slyfox-mal 1]

you could go to your local gunsmith or club and ask if they will chrono it for ye probs only cost ye a couple of quid

oh ye and hope to f**K its under 12lbs/f

or ye may not get it back lol

It actually works out the opposite spike.

See this site for pellet weights and power produced, found it useful

Anything over 12 ft/lbs will be classed as a firearm. Even if it's 0.00000000000000000000000000000000000000000000001. Factory rifles are set up so they can't go over 12ft/lbs, however with amateur gunsmiths there is no guarantee.

 

Buy a chronograph. They cost as little as £40.

 

The police are carrying them and so should you. If your gun is over and you get caught they will make an issue over it.

 

If you buy a gun and you don't check it, it's your fault not that of the guy that sold it to you.
