Guys,

I have been reading most all of the posts here, so far, and I see the following terminology used,
I am not sure what is meant by it, such as,

Pal pertaining to AR's, = ?

12 fpe max, = ?

Why is the ballistics results posted in FPE etc,
does not FPE and FPS mean the same thing?

Still learning AR's.

I have given up on using the search function here,
IMHO, that old search dog should be retired and a new one trained. LOL

Tia,
Don

I can answer one of your questions:

FPE (Foot Pounds Energy) refers to energy while FPS refers to Feet Per Second (or simply the speed of the pellet being used).

In other words the FPE will vary according to the weight of the pellet being used so that it will increase if you use a heavier pellet being shoot at the same FPS.

If your FPS stays constant your FPE will go up or down according to the weight of the pellet being used.

More FPE is usually good if you are trying to kill a pest animal using an air gun at a certain FPS.

Pal pertaining to AR's, = ? Any Airgun over 500 FPS requires a PAL to purchase ( Possession and Acquisition ) License AKA firearm license.

12 fpe max, = ? UK thing where any rifle over 12 FPE requires a firearm license

Why is the ballistics results posted in FPE etc,
does not FPE and FPS mean the same thing? FPE = Foot Pound Energy. FPS Feet Per Second. FPE is the energy a weight of a pellet hit at a speed. Sorta like Torque and HP when comes to engines.

A PAL is required for any air rifle that is rated at over 500 fps and 5.7 joules of energy.

An R-PAL (Restricted PAL) is required for any air pistol that is rated at over 500 fps and 5.7 joules of energy.

FPE is foot pounds energy, not foot pounds equivalency.

The formula for figuring FPE is Speed Squared X bullet weight in grains, divided by the constant 450240 gives the foot pounds energy FPE of the projectile. This is supposed to be the measure of how many pounds can be lifted or moved one foot by the energy of the projectile - which is ridiculous if you think about it, but is the measure used & widely accepted.

FPS is feet per second) simply the projectile speed expressed as the number of feet it will travel in one second of time - usually expressed as muzzle velocity, or average muzzle velocity.

I can chime in on the search menu. This is the same format (forum) as the Excalibur Crossbow forum uses in which I have been a member since 2008. Yes these forums are antique and outdated. :wink: They work well and spammers like them as well. :lol: :lol:

Thanks Guys,
These restrictions (Pal ratings) are for Canadian use only.
OK, now I know. So you have to have a license for Air rifles/pistols, Ouch......

Question,
Would a US citizen have to have a Pal license while in procession of an AR,
when traveling/driving thru Canada, to get to Alaska?

The family wants to take a road trip, sight seeing etc thru Canada,
and then on to Alaska to visit friends, to go fishing etc,
and I wanted to take my QB, 22 cal with me, during the trip etc,
but I don't want to get cross threaded with the border check stations etc.

I know about regular firearms are not allowed in Canada, except for residents etc.

Tia,
Don

If pellet or BB gun is over 500 feet per second it is the same thing as a powder burner in the eyes of the law in Canada. Likely easier to buy a cheapie when you get to Alaska and if you decide to keep it, mail it home to yourself before you leave. :)

Rather than speculate, or expose yourself to the speculation of others who may or may not know...contact Canada Border Services.

It's modern times, how about using Joules?

My wife wears jewels. Since FPE has nothing to do with actual killing power, why figure out what the metric version is?

I use fpe, fps, mpg and mph as well as temperatures in Fahrenheit. Some cross/conversions to metric I know & use, the ones I don't, I don't care about.
