Thinking out loud here, while attempting to steer the thread back to the issue of pellet guns vs. replica/prohib device...
In this particular case, we're not talking about importation so we can leave the CBSA out of it for a moment. What we're discussing is the legal transfer of a gun that IS, or IS NOT considered to be a replica firearm, thus also deemed a prohibited device and thus cannot be transferred/sold without lawful excuse. Correct me if I am wrong but it seems to me the tie-in to "replica" stems both from the muzzle velocity being greater than 407 fps but less than 500 fps, and the close physical resemblence of the pellet gun to it's louder and much more deadly counterpart. However,
both of these conditions must be met in order to classify the gun as a replica, not one or the other.
Having the muzzle velocity for a lightweight (SIMILAR TO AIRSOFT PROJECTILES) .177 projectile above 407 fps, according to the oft-quoted RCMP ballistics report,
will likely result in injury, thus the gun cannot be classified as a "replica" by its very definition of not normally being able to cause injuries. However, exceeding 500 fps will put it into the category of a "firearm", thus requiring PAL/RPAL etc. procedures.
Therefore, to me it seems that the pellet gun operating between 407 and 500 fps with .177 pellets, regardless of accurate physical resemblence to the real fierearm, cannot be deemed a replica by its very definition. Since it is neither a firearm nor a replica, it can be sold (and imported if the CBSA were to get their facts straight). The sweet spot then is between 407 and 500 fps, or whatever the equivalent muzzle energy limits are in Joules.
It is also this "sweet spot" of fps/muzzle energy that airsoft guns could be manufactured against for the very same reasons as the pellet guns. If the manufacturers clearly label these items as "Airguns, 408-499 fps, 0.2g BBs Only" or something like that, then perhaps we'd be in the clear to import them ourselves?? However to clear the way for that particular utopian dream, I would think it would take a number of successful but fairly expensive, up-hill battles requiring exceptionally competent legal representation on our parts, to be waged at the Customs Tribunal and/or Federal Court in order to prove to the CBSA that they have been seizing these items in error. Wishful thinking I suppose...having a Gov't department reverse its long-standing practices because they were actually proven to be wrong all along! Ugh...what was I thinking, they could just go and "fix" the definiton of a replica and we'd be back to square one, but then again so would the pellet gun types! [...sarcasm...]
The thought was nice though while it lasted...
