My DIY pellet trap

Don't know anything about the fx but my gamo was damaging pellets off its mag system.
It would seem to me that any system that requires a pellet to be pushed through one chamber to another with no way correcting a slightly off line pellet, weather it be it was undersized, or oversized, it runs the risk of damaging a pellet.
There is also the problem of the probe possibly not fitting a pellet as well as it should (no one seems to make pellet specific probes) (I'll have one for hades and one for AA field in 22 Pauly 😁) and causing a pellet to move from the mag to barrel.Espially if there is a big lead in to the rifling.
Even in single shot with the 1322 I have times when the pellet starts grab as I push it with the bolt. To correct this I point the gun down and correct with my finger, where upon it tends to fall happily all the way into the barrel.
Air rifle mags don't load a whole cartridge and as such don't have a long brass cylinder to help with alignment. Any misalignment is going to directly affect the projectile.
Though this can be reduced with tight tolerance on parts, if your not sorting pellets you still run into the issue of missized pellets.
I'm assuming a slug would receive damage along the sloped edge and nose if this were to happen.
This is my view and I have never done any testing to back this up.
I think any mag has the potential to damage a pellet and the alignment of the system and the amount of play between the mag and rifling engagement is going to be a big factor in this.
As I said, this is speculation on my behalf and is not backed up by any data I have to hand.

In theory, if the pellet probe was a similar size to the pellet, it would  "hold back" the force of the spring loaded revolving mag from closing on the skirt of the pellet.

It's  a pretty cool gun but now relegated to a future project as it was faulty when I bought it off Gun City.  It's got plenty of power (reputedly 60ftlb) but the mag stopped rotating soon after I got it.  The push lever was well worn and I've played around with it but still needs more work.  It's also started leaking air between the cylinder and the breach as my makeshift seal hasn't worked so it blows air back into your eye
