I've seen that new legislature allows that no liscence is required for any air rifle under .22 cal.
Is there any restriction on the energy output on a .177 cal?
I stand under correction here, but as far as I know there is no power limit under the SA law regarding air rifles / pistols. However if you intend on competing in Field Target or Hunter Field Target disciplines then (12ft/lbs or 16 Joules. As far as I know the UK rules apply to those disciplines. Might even get changed now that SAAFTA has formed.
Simon / Avion,
under FCA (FireArms Control Act) there is no limit on the power / energy produced by a .177 or even a .20 airrifle - YOU DON'T NEED A LICENCE
You also don't need a licence if your .22 airgun that produces less than either 6 or 8 Joules (can't remember exact output).
SAFTAA will not allow anything but a .177 airgun in it's competitions, power limit will also stay at 12ft/lbs to stay in line with the "rest" of the world.
My personal advice, stay away from .20 and .22 for many reasons, don't start walking on a fine line with the law and also because you will not be allowed to shoot FT with it.
Just for info I bought HW100 from Target Specialist in boksburg and he know's how to adjust the power.
For info if you have chrono you can do it yourself.
Take stock off and at the back is a cap that comes off with a big allenkey skrew.
You have to first remove the little allenkey skrew before adjusting otherwise it will not move.
That is as simple as it gets.
My NJR sets in exactly the same way.
It's really not that difficult.
But you definately need a Chrony to measure the speed and only make small adjustments at a time
Ideally the rifle should be filled as you normally do, and then before adjusting fire atleast 10 shots to stabilise the gun (especially on guns that's not regulated), after this begin with adjustments.
To work out the power you ofcourse have to know the pellet weight so that you know at what speed it must be set.
