That leaves Maximus as the only one on this thread worth listening to

Energy( measured as ft/lbs is usually quote as "at the muzzle" and is a function of projectile weight and velocity. Obviously as the projectile travels down range the velocity degrease as a function of the projectile's BC( Ballistic coeficient). Soooo , as you increase the projectlle mass the velocity decreases to a " cross over" point where the energy decreases., and the limitation is the energy available from the air rilfle's mechanism. So there.
Sold my 50 cal. target rifle 1 year ago; when I moved to Mrexico.
In both the USA and UK a silencer is considered a firearm in addition to the weapon itself. They are not in Mexico, but are difficult to obtain. In Mexico, firearms ( not air rifles) are basically illegal unless you obtain a permit from the Miltary.and these are nearly impossible to obtain.
Silencers in the USA cost around $350.00 and you need to pay a $200 tax on a federal permit which I cannot get as I do not have a physical address in the USA.. They are less that $100.00 in the UK.
Hope this explains my dilema.
However, there is a solution. Purchase an air rifle with a built in silencer called a "shroud" As it is not detachable and therefore tranferable to a true firearm it is not classed as a firearm in both UK and USA.
Have I bored you enough yet.?
