One for MB , Vics vapour rub

SS your restrictions are on the energy produced by the rifle no matter how that energy is obtained. Increasing velocity over that required to reach your 12 pound threshold, no matter how it is done, puts you in illegal territory.

I do not know if the use of Vicks works or not. All the hocus-pokus I have ever dealt with along these lines involved special mixtures of lube for muzzle loading rifles. Some people claim that lubes used to patch the ML balls are speeded up or slowed by lube. It never made any real difference that I could tell across the chronograph and I tested everything from spit to some serious blends of crap, one of which was officially known as "Moose Snot" and made from lanolin, Murphy oil soap, bees wax, and turpentine.

However I doubt that Vicks will do any real damage to your seals or your spring since we have many of the same models over here but they are equipped with a spring to propel a .177 pellet to 1000fps and hold up for years.

My own serious air rifle is a Beeman, probably made in China or Turkey, I am not sure. It is a .22 and lobs the pellet out at nearly 900fps. I seldom use is since it is heavier than a 105 howitzer.

Most of its reason for existence is a comical continuing drama where I shoot close to the neighborhood feral cats as they hunt in the field and they scoot for cover when they hear the pellets land in the grass nearby. Apparently they come pretty close at 100 yards or so since the cats take notice of them landing.

I have often thought that if I was not going to get an FAC, and I was restricted to your air guns and your laws, I would have an American made full power spring for my rifle hidden in a PVC tube and hidden in a garden planter.
